Sort the manga catalog by created / updated / title / author with an
independent asc/desc direction control. An omitted `order` defaults per field
(dates newest-first, text A→Z), matching the UI, so a bare `?sort=<field>`
means the same thing in the browser and over the API; `sort=recent` remains a
back-compat alias for `created`.
- Backend: SortField/SortOrder parsed with validation (structured 422 on bad
input), per-field default_order, NULLS LAST only on the nullable author key,
and migration 0033 indexing mangas(updated_at DESC, id) to back the default
sort and its id tie-break.
- Frontend: catalog sort field + direction (SegmentedControl) on desktop and a
mobile bottom sheet; pure helpers in $lib/mangaSort; keyboard-accessible
direction control; visible Direction labels and a sheet "Done" button.
- Tests: backend integration coverage (defaults, alias, invalid input,
ascending-id tie-break), frontend unit + e2e.

Phase 2 of the mobile redesign: the catalog at `/` adapts to phone
viewports without disrupting the desktop layout. The same filter form
renders inline on desktop and inside a bottom sheet on mobile, and a
dedicated sort sheet replaces the inline `<select>` below 640px.
- MangaCard gains optional `unreadCount` and `progress` props that
render a top-right pill badge and a bottom progress overlay on the
cover. Both are no-ops when omitted, so existing callers don't
change. Counts past 99 cap at "99+".
- The filter form body is extracted into a Svelte 5 snippet and
rendered conditionally — inline desktop panel OR mobile sheet, never
both — so no testid is duplicated and the focus trap can't double-
fire. A matchMedia listener tracks the 640px breakpoint and drives
the snippet target.
- Mobile catalog adds: Filter / Sort chip buttons, an always-visible
active-filter chip row with per-facet remove buttons, full-width
search, and a 2-column grid.
- Auto-expanding the filter panel from URL params is now desktop-only
— on mobile the active-filter chips signal applied facets without
hiding the catalog under a scrim on first paint.
- Vitest suite covers MangaCard badge / overlay behavior including
clamp / hide edge cases. Playwright spec covers the mobile filter +
sort sheet flow at 390px viewport, with a hydration gate to keep
click dispatch from racing the SSR'd-but-not-yet-reactive button.
