- Header: sticky app-wide, active nav highlighting, data-driven theme
picker with active swatch, unified SVG icons, deduped login fragment
(was duplicated verbatim for desktop + mobile), removed stray console.log
- LibrarySwitcher: cleaner sticky bar, SVG action icons, theme-aware
- BookCard: the atomic unit now has a real surface (was floating text
when wood-paneling was off due to an undefined --wood-border), with
cohesive shadow + hover lift; reused across dashboard/bookshelf/series
- Dashboard: calmer section headers, snap carousels with SVG chevrons
- Bookshelf: recompose the filter wall into a search toolbar + collapsible
Filters panel (all 9 filters + save/load/clear preserved), redesigned
empty state and pagination
- Book detail, series, collections, browse: cohesive cards, SVG action
icons, uppercase muted labels, theme-aware badges/links
