Slice 2 of the cover-caching pass. SyncController now downloads cover
bytes for newly-upserted albums + playlists into the shared
flutter_cache_manager disk cache after each sync transaction commits.
A cold-start scroll through the home grid paints from disk on the very
first frame instead of firing one HTTP per visible tile.
Best-effort: fire-and-forget after commit, concurrency 3, per-URL
failures swallowed (404 for collages that haven't built yet, 401
during token-refresh races). Artist covers skipped — ArtistRef.coverUrl
is server-derived from "most-recent album" and not reconstructible
client-side; album pre-warm already covers the artist's primary visual.
Auth header reuses sessionTokenProvider for parity with ServerImage.
Slice 1 of the cover-caching pass. The previous Image.network /
NetworkImage path only cached covers in memory, so a scroll-off + scroll-
back or an app restart re-downloaded every tile from the server. Swap
to cached_network_image so bytes land on disk (path_provider temp dir,
URL-keyed) and survive both.
Sites migrated:
- ServerImage (all /api/*/cover usage — home grid, library, playlist,
artist/album detail headers)
- DiscoverScreen Lidarr suggestion thumbnails
- PlayerBar mini cover (HTTPS branch; file:// branch unchanged since
AlbumCoverCache files are already on disk)
Auth header forwarding preserved via httpHeaders. Fade-in disabled so
populated grids paint instantly on cache hit.
Slice 2 (pre-warm during sync) builds on this same cache manager.
Three of the four locked items (1, 2, 4); item 6 (swipe-tabs) stays
deferred until server-side lyrics ingestion exists.
1. Dominant-color gradient backdrop. New album_color_extractor.dart
wraps the existing AlbumCoverCache: extracts the dominant color
via PaletteGenerator over the local file, caches in-memory keyed
by album_id. Top 55% of the screen carries the color (0.55 alpha
→ fs.obsidian) so controls below stay legible. AnimatedContainer
tweens the gradient across track changes.
2. Hero transition for cover art (mini bar → full screen). Stable
kPlayerCoverHeroTag (not media.id keyed) so the transition works
regardless of what's playing and isn't racy if media swaps mid-tap.
flightShuttleBuilder renders the destination's Hero widget for the
whole flight, which reads as a clean grow rather than a swap.
4. Crossfade on track change. AnimatedSwitcher around the album art,
title, and artist+album text block, all keyed by media.id so the
switcher fades between old and new on each track-change rebuild.
Pairs with the AnimatedContainer gradient so the whole "what's
playing" zone changes in lockstep.
palette_generator: ^0.3.3 added.
For #396 / #356 umbrella.

Flutter client posts FlutterTimezone.getLocalTimezone() to
PUT /api/me/timezone on every setSession (login / register success)
and on every AuthController.build (app cold-start with valid
session), when the locally-stored tz_last_sent_at is >7 days old.
Cadence tracked in flutter_secure_storage so it survives app
restarts.
Failures swallowed: the server's UTC default + last-known value
keep the scheduler functioning until the next attempt.
Completes the client side of #392 Half B (per-user timezone
scheduling).

Player bar: drop the volume slider — phone hardware controls volume.
Right cluster collapses to a single row of shuffle/repeat/queue.
Playlist card: GestureDetector defers to children by default, so taps
over the cover image area didn't always register. Add HitTestBehavior.opaque
so the whole card surface is tappable.
Update banner: was 3-4× the height of its text — IconButton's default
48dp tap target plus generous vertical padding dominated. Tighten
padding (8→4), shrink dismiss button to 32×32 with iconSize 16, slim
the action button to 28dp height with shrinkWrap tap target.
Home screen: ClampingScrollPhysics + 140dp bottom padding (already
applied in working tree) so scroll stops just above the mini-player.
iOS + Android targets only; desktop disabled (per spec, Tauri-wrapped
SvelteKit handles desktop in v1.1). Riverpod + dio + just_audio +
audio_service + go_router pinned in pubspec. Smoke test confirms the
ProviderScope wiring boots a Material app.
