-                    GNU AFFERO GENERAL PUBLIC LICENSE
-                       Version 3, 19 November 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-our General Public Licenses are intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
-
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
-
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+GNU GENERAL PUBLIC LICENSE
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <https://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and other kinds of works.
+
+The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and modification follow.
+
+TERMS AND CONDITIONS
+
+0. Definitions.
+
+“This License” refers to version 3 of the GNU General Public License.
+
+“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
+
+“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be individuals or organizations.
+
+To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.
+
+A “covered work” means either the unmodified Program or a work based on the Program.
+
+To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
+
+To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
+
+1. Source Code.
+The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.
+
+A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
+
+The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
+
+The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same work.
+
+2. Basic Permissions.
+All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
+
+4. Conveying Verbatim Copies.
+You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
+
+5. Conveying Modified Source Versions.
+You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
+
+     a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
+
+     b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
+
+     c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
+
+     d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
+
+6. Conveying Non-Source Forms.
+You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
+
+     a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
+
+     b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
+
+     c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
+
+     d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
+
+     e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
+
+A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
+
+“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
+
+The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
+
+7. Additional Terms.
+“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
+
+     a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
+
+     b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
+
+     c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
+
+     d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
+
+     e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
+
+     f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
+
+8. Termination.
+You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
+
+9. Acceptance Not Required for Having Copies.
+You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
+
+10. Automatic Licensing of Downstream Recipients.
+Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
+
+An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
+
+11. Patents.
+A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.
+
+A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
+
+In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
+
+A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
+
+12. No Surrender of Others' Freedom.
+If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
+
+13. Use with the GNU Affero General Public License.
+Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
+
+14. Revised Versions of this License.
+The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
+
+Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
+
+15. Disclaimer of Warranty.
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. Limitation of Liability.
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+17. Interpretation of Sections 15 and 16.
+If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full notice is found.

+
+**Timezone selection:** Manual dropdown only (no browser auto-detect)
+
+---
+
+## Phase 1: Database Schema
+
+**File:** `database/schema/schema.sql`
+
+1. Add `timezone` column directly to the `users` table definition (line ~36):
+
+```sql
+CREATE TABLE IF NOT EXISTS users (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    email VARCHAR(255) UNIQUE NOT NULL,
+    username VARCHAR(255) UNIQUE NOT NULL,
+    password_hash VARCHAR(255) NOT NULL,
+    first_name VARCHAR(255),
+    last_name VARCHAR(255),
+    role VARCHAR(20) NOT NULL DEFAULT 'user' CHECK (role IN ('admin', 'user')),
+    theme VARCHAR(50) DEFAULT 'tokyo-night',
+    max_devices INTEGER DEFAULT 10,
+    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
+    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
+    timezone VARCHAR(50) DEFAULT 'UTC'
+);
+```
+
+> Note: The `timezone` column is already present at line 36 in the current schema. No change needed for this step.
+
+1. Add `default_timezone` to the `system_settings` INSERT block (line ~49-52):
+
+```sql
+INSERT INTO system_settings (setting_key, setting_value, description) VALUES
+('scan_poll_interval_seconds', '60', 'How often to scan all libraries in minutes'),
+('auto_scan_enabled', 'true', 'Whether auto-scanning is enabled system-wide'),
+('default_timezone', 'UTC', 'System default timezone')
+ON CONFLICT (setting_key) DO NOTHING;
+```
+
+1. Add index in the indexes section (after line ~460, with other user indexes):
+
+```sql
+CREATE INDEX IF NOT EXISTS idx_users_timezone ON users(timezone);
+```
+
+1. Regenerate sqlc code:
+
+```bash
+cd internal/database && sqlc generate
+```
+
+---
+
+## Phase 2: Database Queries
+
+**File:** `internal/database/queries/queries.sql`
+
+Add new queries:
+
+```sql
+-- name: UpdateUserTimezone :exec
+UPDATE users SET timezone = $2, updated_at = NOW() WHERE id = $1;
+
+-- name: GetSystemTimezone :one
+SELECT setting_value FROM system_settings WHERE setting_key = 'default_timezone';
+```
+
+> Note: `UpdateSystemTimezone` is omitted because the existing `UpdateSystemSetting` query handles it by passing `'default_timezone'` as the key parameter.
+
+Regenerate after adding queries:
+
+```bash
+cd internal/database && sqlc generate
+```
+
+---
+
+## Phase 3: Template Utilities
+
+**File:** `templates/utils.go`
+
+Add timezone-aware time formatting helpers:
+
+```go
+package templates
+
+import (
+    "time"
+
+    "github.com/jackc/pgx/v5/pgtype"
+)
+
+// FormatInTimezone formats a time.Time in the specified timezone as MM-DD-YYYY HH:MM
+func FormatInTimezone(t time.Time, timezone string) string {
+    if t.IsZero() {
+        return ""
+    }
+
+    loc, err := time.LoadLocation(timezone)
+    if err != nil {
+        loc = time.UTC
+    }
+
+    return t.In(loc).Format("01-02-2006 03:04 PM")
+}
+
+// FormatTimestamptzInTimezone formats a pgtype.Timestamptz in the specified timezone
+func FormatTimestamptzInTimezone(t pgtype.Timestamptz, timezone string) string {
+    if !t.Valid {
+        return ""
+    }
+    return FormatInTimezone(t.Time, timezone)
+}
+```
+
+---
+
+## Phase 4: User Context Update
+
+**File:** `templates/types.go`
+
+Add `Timezone` field to the `User` struct:
+
+```go
+type User struct {
+    ID        string
+    Email     string
+    Username  string
+    Role      string
+    Theme     string
+    FirstName string
+    LastName  string
+    CreatedAt time.Time
+    Token     string
+    Timezone  string
+}
+```
+
+**File:** `internal/router/helpers.go`
+
+Update `getTemplateUserWithTheme()` to include timezone:
+
+```go
+userTimezone := "UTC"
+if userDB.Timezone.Valid {
+    userTimezone = userDB.Timezone.String
+}
+
+return templates.User{
+    // ... existing fields ...
+    Timezone: userTimezone,
+}
+```
+
+---
+
+## Phase 5: Handlers
+
+**File:** `internal/handlers/auth.go`
+
+Update `UpdateProfileRequest` struct:
+
+```go
+type UpdateProfileRequest struct {
+    Username  string `json:"username,omitempty" validate:"omitempty,min=3,max=50"`
+    Email     string `json:"email,omitempty" validate:"omitempty,email"`
+    FirstName string `json:"first_name,omitempty" validate:"omitempty,max=100"`
+    LastName  string `json:"last_name,omitempty" validate:"omitempty,max=100"`
+    Theme     string `json:"theme,omitempty" validate:"omitempty"`
+    Timezone  string `json:"timezone,omitempty" validate:"omitempty"`
+}
+```
+
+Add timezone update logic in `UpdateProfile()`:
+
+```go
+if req.Timezone != "" {
+    if _, err := time.LoadLocation(req.Timezone); err != nil {
+        return c.JSON(http.StatusBadRequest, map[string]string{
+            "error": "Invalid timezone",
+        })
+    }
+    err := h.db.UpdateUserTimezone(ctx, database.UpdateUserTimezoneParams{
+        ID:       pgtype.UUID{Bytes: userUUID, Valid: true},
+        Timezone: pgtype.Text{String: req.Timezone, Valid: true},
+    })
+    if err != nil {
+        return err
+    }
+}
+```
+
+**File:** `internal/handlers/system_settings.go`
+
+Add timezone settings handler:
+
+```go
+type UpdateTimezoneSettingsRequest struct {
+    DefaultTimezone string `json:"default_timezone" validate:"required"`
+}
+
+func (h *SystemSettingsHandler) UpdateTimezoneSettings(c *echo.Context) error {
+    var req UpdateTimezoneSettingsRequest
+    if err := c.Bind(&req); err != nil {
+        return c.JSON(http.StatusBadRequest, map[string]string{"error": "Invalid request"})
+    }
+    if _, err := time.LoadLocation(req.DefaultTimezone); err != nil {
+        return c.JSON(http.StatusBadRequest, map[string]string{"error": "Invalid timezone"})
+    }
+    err := h.db.UpdateSystemSetting(c.Request().Context(), database.UpdateSystemSettingParams{
+        SettingKey:   "default_timezone",
+        SettingValue: req.DefaultTimezone,
+    })
+    if err != nil {
+        return err
+    }
+    return c.JSON(http.StatusOK, map[string]string{"message": "Timezone updated"})
+}
+```
+
+---
+
+## Phase 6: User Profile UI
+
+**File:** `templates/profile_form.templ`
+
+Add timezone dropdown after the theme field:
+
+```templ
+<div class="form-group">
+    <label for="timezone">Timezone</label>
+    <select name="timezone" id="timezone" class="form-select">
+        <option value="UTC" selected?={ user.Timezone == "UTC" }>UTC (Coordinated Universal Time)</option>
+        <option value="America/New_York" selected?={ user.Timezone == "America/New_York" }>Eastern Time</option>
+        <option value="America/Chicago" selected?={ user.Timezone == "America/Chicago" }>Central Time</option>
+        <option value="America/Denver" selected?={ user.Timezone == "America/Denver" }>Mountain Time</option>
+        <option value="America/Los_Angeles" selected?={ user.Timezone == "America/Los_Angeles" }>Pacific Time</option>
+        <option value="America/Phoenix" selected?={ user.Timezone == "America/Phoenix" }>Mountain Time (no DST)</option>
+        <option value="America/Anchorage" selected?={ user.Timezone == "America/Anchorage" }>Alaska Time</option>
+        <option value="Pacific/Honolulu" selected?={ user.Timezone == "Pacific/Honolulu" }>Hawaii Time</option>
+    </select>
+</div>
+```
+
+Include timezone in the HTMX form submission payload.
+
+---
+
+## Phase 7: Admin Settings UI
+
+**File:** `templates/admin_settings.templ`
+
+Add system default timezone setting:
+
+```templ
+<div class="setting-group">
+    <h3>System Defaults</h3>
+    <label for="default_timezone">Default Timezone</label>
+    <select name="default_timezone" id="default_timezone">
+        <option value="UTC">UTC (Coordinated Universal Time)</option>
+        <option value="America/New_York">Eastern Time</option>
+        <option value="America/Chicago">Central Time</option>
+        <option value="America/Denver">Mountain Time</option>
+        <option value="America/Los_Angeles">Pacific Time</option>
+        <option value="America/Phoenix">Mountain Time (no DST)</option>
+        <option value="America/Anchorage">Alaska Time</option>
+        <option value="Pacific/Honolulu">Hawaii Time</option>
+    </select>
+</div>
+```
+
+---
+

+
+For `time.Time` fields:

+
+## Testing Checklist
+
+- [ ] Create user, set timezone to Eastern, verify times display in MM-DD-YYYY HH:MM format
+- [ ] Create user, set timezone to Pacific, verify different offset
+- [ ] Test system default timezone fallback for users with no timezone set
+- [ ] Verify invalid timezone values are rejected by the API
+- [ ] Verify existing users (no timezone set) fall back to system default
+- [ ] Verify all templates show consistent MM-DD-YYYY HH:MM format
+- [ ] Run `make test-integration` to verify no regressions
+
+---
+
+## Deployment Steps
+
+1. Update `database/schema/schema.sql` with new column and settings
+2. Regenerate sqlc: `cd internal/database && sqlc generate`
+3. Apply schema changes (restart database container with `make rebuild-force-db`)
+4. Deploy backend code changes
+5. Verify with existing data

--- two or more media_items in the same library share a file_sha256 but live at
--- different file paths (e.g. the same book imported twice under two names on
--- a preexisting database). Unlike path duplicates these cannot be auto-collapsed
--- (keeping both copies may be intentional), so each group is surfaced on the
--- admin Hash Conflicts page for the user to resolve:
---   keep_all      - both copies are intentional; just stop flagging
---   kept:<uuid>   - merge every other copy's child rows into the kept item
---                   (via reparent_media_item_children) and delete the losers

-# Hash Conflicts API
-
-## Overview
-
-When Bookhoard hashes your library (on import, rescan, or the startup backfill), two media items in the same library with the same `file_sha256` indicate duplicate content. Each duplicate group is recorded as a **hash conflict** and exposed here for an explicit keep/merge decision. Conflicts are also surfaced in the admin UI's Hash Conflicts page.
-
-**Authentication**: Admin JWT token required
-**Content-Type**: `application/json` (resolve also accepts form-encoded bodies for htmx)

-## When Conflicts Are Created
-
-- **Startup backfill**: items imported before hashing existed are hashed automatically ~30s after startup; duplicates discovered land here.
-- **Rescan**: hashes are recomputed and content duplicates are flagged.

-
-### Color Semantics
-
-KOReader paints highlights from a fixed palette of color names; the web reader uses hex swatches. Colors are mapped at the boundary (unmappable values fall back to yellow on both sides):
-
-| KOReader name | Web hex   |
-| ------------- | --------- |
-| yellow, orange | `#ffd54f` |
-| green, olive  | `#a5d6a7` |
-| cyan, blue    | `#90caf9` |
-| purple        | `#ce93d8` |
-| red           | `#f48fb1` |
-
-- An echo (device re-reporting an annotation it received from the server) carries **no color**, so the stored web color is never clobbered.
-- A non-empty color means the user edited the highlight on the device; it is mapped to the nearest web swatch.

-
-## Deletion propagation
-
-The progress push is upsert-only: absence of an annotation from
-`highlights`/`notes`/`bookmarks` is **never** interpreted as a delete (a
-client with a category disabled must not wipe the server). Deletions are
-reported explicitly:
-
-- Devices remember the `dedup_key` of every annotation the server served
-  them (persisted locally, e.g. KOReader's sidecar `bookhoard_known_keys`).
-- When one of those annotations no longer exists locally, the next push
-  lists its key in `deleted_highlights` / `deleted_bookmarks`.
-- The server tombstones the matching rows (`deleted = TRUE`, kept for the
-  retention window). Tombstones are served back to *other* devices via the
-  metadata fetch's `deleted_highlights` / `deleted_bookmarks` arrays so the
-  deletion converges everywhere.
-- A stale replay pushing the annotation's content cannot resurrect the
-  tombstone: device pushes carry no modification timestamp, so the save is
-  treated as older than the delete.
-- Restoring is possible from the web book page's deleted-annotation
-  history (`GET /api/media-items/:id/annotations/deleted`, restore/purge
-  endpoints) until the retention window lapses.
-
-Because keys are only learned from server pulls, a device-native annotation
-deleted locally is simply never pushed again — it can never be mis-flagged
-as a server annotation deletion.
-
-## Book identification
-
-Every client/sync interface (KOReader, Kobo, OPDS, the device-link UI, and any
-future mobile app) resolves books through a single shared service:
-[`internal/services/book_resolver.go`](../../../internal/services/book_resolver.go).
-The import-time SHA-256 (stored on `media_items.file_sha256`, plus a per-format
-hash on `media_item_formats.file_sha256` for KEPUB/PDF) is the canonical shared
-identifier. New clients should resolve by SHA-256 via `BookResolver` rather than
-re-implementing their own matcher.

-The System Settings API is the canonical way to read and write Bookhoard's tunable system settings (scanning, security, rate limits, sync, performance, and defaults). Every setting carries full metadata — type, range, category, description, and whether a restart is required — so the admin UI (and API clients) can render and validate settings generically.
+The System Scan Settings API allows administrators to configure system-wide scan settings that apply to all libraries. These settings control the automatic scanning behavior for the entire Bookhoard system.

-The older JSON routes still work for backward compatibility and now refresh the settings registry cache on write, but they are **superseded** by `GET/PUT /api/system/settings`:
-
-- `GET /api/libraries/scan-settings` — returns only `scan_poll_interval_seconds` and `auto_scan_enabled`
-- `PUT /api/libraries/scan-settings` — accepts `{ "scan_poll_interval_seconds": int, "auto_scan_enabled": bool }`
-

+## Migration Notes
+
+This API has been updated to use a new polling-based scanning system. The following changes were made:
+
+- **Changed**: `scan_frequency_minutes` renamed to `scan_poll_interval_seconds`
+- **Changed**: Unit changed from minutes to seconds (15-1440 minutes → 1-3600 seconds)
+- **Removed**: Old scheduler-based scanning system
+- **Added**: Real-time file watching with polling fallback
+- **Preserved**: API endpoint paths remain the same
+
+The new system ensures that:
+
+1. File changes are detected in real-time when possible (via fsnotify)
+2. Polling fallback catches missed events at the configured interval
+3. Settings apply to all libraries system-wide
+4. Only administrators can modify scan settings
+5. The `auto_scan_enabled` setting controls both file watching and polling

 # Kobo Device Setup Guide
 
-> ## 🚧 Coming Soon
->
-> Native Kobo sync is not available yet. It is actively being developed and this guide will be filled in as the feature lands.
+This guide will help you set up your Kobo e-reader to sync with Bookhoard for seamless cross-device reading progress synchronization.
 
-## Using a Kobo With Bookhoard Today
+## What is Kobo Sync?
 
-You don't have to wait: **KOReader runs on Kobo hardware** and syncs fully with Bookhoard today — reading position, bookmarks, highlights, and notes, plus OPDS wireless book delivery.
+Bookhoard implements a Kobo-compatible sync protocol that allows your Kobo device to:
 
-See the **[KOReader Setup Guide](koreader-setup.md)** for complete instructions.
+- Sync reading progress across all your devices
+- Sync highlights and bookmarks
+- Sync reading statistics
+- Maintain device-specific metadata
 
-## What's Planned for Native Kobo Sync
+## Prerequisites
 
-When released, native Kobo sync will let stock Kobo firmware talk directly to Bookhoard:
+Before you begin, make sure you have:
 
-- **Reading position sync** — percentages, pages, and reading statistics
-- **Bookmarks, highlights, and notes** — synced with the web and other devices
-- **OPDS wireless delivery** — browse and download books directly on the Kobo
-- **Automatic EPUB → KEPUB conversion** — for better Kobo rendering
-- **Shelf mappings** — Bookhoard collections appearing as Kobo shelves
+- ✅ A Kobo e-reader device (Clara, Aura, Nia, Libra, Sage, Elipsa, etc.)
+- ✅ A Bookhoard instance running and accessible on your network
+- ✅ Your Bookhoard credentials (username and password)
+- ✅ USB cable to connect your Kobo to your computer
+- ✅ Your Kobo connected to the same Wi-Fi network as your Bookhoard instance
 
-The server-side protocol endpoints are already implemented and under test; the feature will be announced when it's ready for real devices.
+## Supported Kobo Devices
 
-## FAQ
+Bookhoard supports all Kobo devices that use the standard Kobo sync protocol:
 
-**Q: Should I buy a Kobo to use with Bookhoard today?**
-A: Kobo devices work great with Bookhoard via KOReader. Native (stock firmware) sync is coming soon.
+- **Kobo Clara**: Clara 2E, Clara HD
+- **Kobo Aura**: Aura, Aura H2O, Aura ONE, Aura Edition 2
+- **Kobo Libra**: Libra 2, Libra H2O
+- **Kobo Forma**: All versions
+- **Kobo Sage**: All versions
+- **Kobo Elipsa**: All versions
+- **Kobo Nia**: All versions
+- **Kobo Touch**: Touch 2.0
+- **Kobo Glo**: Glo, Glo HD
 
-**Q: What happens to my KOReader setup when native sync arrives?**
-A: Nothing — KOReader will keep working. Native sync simply adds another option for people who prefer stock Kobo firmware.

+2. Navigate to `.kobo/Kobo/Kobo eReader.conf`
+3. Open in a text editor
+
+### Step 3: Add Bookhoard Sync Configuration
+
+After device registration is complete, you'll receive an API key and sync URL from Bookhoard.
+
+Add the following section to the end of your `Kobo eReader.conf` file:
+
+```ini
+[FeatureSettings]
+# Enable Kobo store replacement
+KoboStoreSyncDisabled=true
+
+[Sync]
+# Bookhoard Sync Configuration (from Device Management page)
+ServerURL=http://YOUR_COMPUTER_IP:8765/api/sync/kobo/YOUR_API_KEY
+AutoSyncEnabled=true
+SyncFrequency=5
+```
+
+**Where to find these values**:
+
+- `YOUR_COMPUTER_IP`: Your Bookhoard server's IP address (e.g., 192.168.1.100)
+- `YOUR_API_KEY`: Copy from Bookhoard Device Management → Your Kobo Device → "Copy Sync URL"
+
+**Example configuration**:

+- `YOUR_BOOKHOARD_USERNAME`: Your Bookhoard email or username
+- `YOUR_BOOKHOARD_PASSWORD`: Your Bookhoard password
+
+**Example configuration:**
+
+```ini
+[Sync]
+ServerURL=http://192.168.1.100:8765/api/sync/kobo
+AutoSyncEnabled=true
+SyncFrequency=5
+Username=john@example.com
+Password=securePassword123
+```
+
+### Step 4: Save and Eject
+
+1. Save the `Kobo eReader.conf` file
+2. Safely eject your Kobo device from your computer
+3. Kobo will restart automatically
+
+### Step 5: Verify Sync on Kobo

+
+**Problem**: Sync doesn't happen automatically
+
+**Solutions**:
+
+1. Check Kobo is connected to Wi-Fi
+2. Verify `AutoSyncEnabled=true` in config
+3. Check `SyncFrequency` is not set to 0
+4. Test with manual sync first
+5. Check Bookhoard logs for connection attempts
+
+### Connection Refused
+
+**Problem**: "Connection refused" or "Server not reachable"
+
+**Solutions**:
+
+1. Verify Bookhoard is running on your computer
+2. Check the server URL and IP address are correct
+3. Ensure Kobo is on same Wi-Fi network as computer
+4. Temporarily disable firewall to test
+5. Try accessing Bookhoard URL in your browser first
+
+### Authentication Failed
+
+**Problem**: "Authentication failed" or "Invalid API key"
+
+**Solutions**:
+
+1. Verify the API key in your sync URL matches the one in Bookhoard Device Management
+2. Check that device is approved in Bookhoard (not pending)
+3. Try regenerating the API key from Device Management page
+4. Ensure the sync URL is complete (includes the API key)
+5. Copy the sync URL directly from Device Management → "Copy Sync URL" button
+
+### Configuration File Not Saving
+
+**Problem**: Changes to `Kobo eReader.conf` are lost
+
+**Solutions**:
+
+1. Make sure Kobo is ejected safely after editing
+2. Check file permissions (should be writable)
+3. Try a different text editor (Notepad++, VS Code, Sublime Text)
+4. Backup the file before editing
+5. On Mac, ensure you're not editing the package directly
+
+### Sync Only Works Manually
+
+**Problem**: Manual sync works, but auto-sync doesn't
+
+**Solutions**:
+
+1. Verify `AutoSyncEnabled=true` in config
+2. Check `SyncFrequency` is not 0
+3. Kobo only syncs when connected to Wi-Fi
+4. Some Kobo models require Wi-Fi to be manually connected
+5. Check Bookhoard device management page for connection errors
+
+### Books Not Appearing in Kobo
+
+**Problem**: Books added to Bookhoard don't show on Kobo
+
+**Solutions**:
+
+1. Kobo needs books to be sideloaded (manually transferred via USB)
+2. Bookhoard syncs PROGRESS, not book files
+3. Transfer book files to Kobo's `Documents` folder via USB
+4. Kobo will then sync progress for those books with Bookhoard
+5. Check that book formats are supported by Kobo
+
+### Conflicts Not Showing
+
+**Problem**: Conflicts between devices aren't being detected
+
+**Solutions**:
+
+1. Check Bookhoard Conflicts page
+2. Ensure both devices have synced recently
+3. Conflicts only detected when progress differs within 5 minutes
+4. Manually sync both devices to trigger conflict detection
+5. Review conflict resolution settings
+
+## Security Best Practices
+
+1. **Use HTTPS**: If deploying Bookhoard publicly, configure SSL/TLS
+2. **Strong Password**: Use a secure password for your Bookhoard account
+3. **Network Security**: Ensure your Wi-Fi network is secure (WPA2/WPA3)
+4. **Regular Updates**: Keep Kobo firmware updated
+5. **Device Authorization**: Only approve devices you recognize
+
+## Network Configuration
+
+### Local Network (Recommended)
+
+For home use, keep Kobo and Bookhoard on the same local network:
+
+```
+Kobo Wi-Fi: 192.168.1.x
+Bookhoard: 192.168.1.x
+```
+
+### Remote Access
+
+For access outside your home network:
+
+1. Set up port forwarding on your router (port 8765)
+2. Configure SSL/TLS on Bookhoard
+3. Use a dynamic DNS service for constant hostname
+4. Update Kobo config with public URL including API key:
+   ```ini
+   [Sync]
+   ServerURL=https://yourdomain.com/api/sync/kobo/YOUR_API_KEY
+   ```
+
+## Performance Optimization
+
+### Battery Life
+
+To extend Kobo battery life:
+
+1. Use longer sync intervals (15-30 minutes)
+2. Sync only on Wi-Fi (not cellular if your Kobo has it)
+3. Disable unnecessary Kobo features
+4. Keep Kobo in sleep mode when not reading
+
+### Sync Speed
+
+To improve sync speed:
+
+1. Ensure strong Wi-Fi signal
+2. Use local network (not remote access)
+3. Keep Bookhoard and Kobo on same network
+4. Close other apps using Wi-Fi bandwidth
+5. Reduce number of books syncing at once

+### OPDS vs USB Transfer
+
+| Feature           | OPDS (Wireless)               | USB Transfer            |
+| ----------------- | ----------------------------- | ----------------------- |
+| **Convenience**   | ⭐⭐⭐⭐⭐ No cable needed    | ⭐⭐ Requires cable     |
+| **Speed**         | ⭐⭐⭐ Fast (Wi-Fi dependent) | ⭐⭐⭐⭐⭐ Very fast    |
+| **Bulk Transfer** | ⭐⭐⭐ One at a time          | ⭐⭐⭐⭐⭐ Many at once |
+| **Progress Sync** | ⭐⭐⭐⭐⭐ Instant            | ⭐⭐⭐⭐ After transfer |
+| **Accessibility** | ⭐⭐⭐⭐⭐ Anywhere           | ⭐⭐ At computer only   |
+| **Reliability**   | ⭐⭐⭐⭐ Very good            | ⭐⭐⭐⭐⭐ Excellent    |
+
+**Recommendation**: Use OPDS for daily reading (convenience), USB for bulk library transfers.
+
+### OPDS Tips and Tricks
+
+1. **Favorite Collections**: Pin frequently-used collections to home screen
+2. **Batch Downloads**: Start multiple downloads before leaving Wi-Fi
+3. **Download Queue**: Downloads continue in background while reading
+4. **Storage Management**: Check free space before downloading large collections
+5. **Network Speed**: Use 5GHz Wi-Fi for faster downloads if available
