Phase 1 of the reader redesign:
- Reading surface is edge-to-edge; top/bottom bars overlay
translucently (backdrop-blur) instead of reserving insets, killing
the inset-coordination bug class entirely. Chrome auto-hides after
2.5s of pointer inactivity (chrome_behavior setting finally wired:
auto-hide / always-visible; legacy values map to auto-hide). Pointer
activity inside page iframes keeps it awake; Esc toggles.
- TOC / Settings / Bookmarks become slide-over drawers with a scrim
(z-50, full-height, safe-area aware), replacing the dockable-panel
system and its window-shade headers. Only one drawer opens at a
time; Esc or scrim click closes.
- Bottom bar is contextual: reflowable keeps nav/slider/progress/TOC;
fixed-layout row adds Fit Page/Width select, zoom cluster,
magnifier (now shows active state), Double Page Spread toggle, and
a Smart | Pan | Text segmented control replacing the cryptic
two-state icon. Smart = text-aware drag; Text = selection-only
(manual smart-detect off); Pan = force pan. Choice persists via
pdf_interaction_mode (new setting + foliate 29bc958 'text' mode).
- Settings drawer: Behavior (chrome, progress mode), Appearance with
18 Kindle-style theme swatches (single source of truth from
THEME_COLORS), Typography, Layout — each scoped by format.
- Keyboard: t/s/b open TOC/settings/bookmark, Esc closes drawers
before toggling chrome, shortcuts skip form inputs; both slider
rows tracked correctly (no duplicate-ID lookups).
- Topbar: Back, title, add-bookmark, bookmarks drawer, Aa settings;
chrome follows user theme.
