Add a selectable Mornye theme with shared glass controls, dialogs, sheets, notifications, and collection headers while retaining Material components.
Update player artwork, lyrics transitions and highlighting, synchronized rolling time labels, volume controls, and compact navigation. Unify metadata, Library, search, and extension surfaces; preserve restored artwork and report extension load failures.
Validation: full Flutter analyzer clean; 713 tests passed and 4 skipped; pinned Dart formatting and diff checks passed; signed ARM64 and ARM32 release APKs built and verified.
- SettingsGroup centers itself at 720dp via its incoming constraint
(not screen width, so groups inside clamped sheets are never
over-inset; unbounded-width contexts guarded); priority scaffold,
bespoke hero cards, and donate page get the same inset - all 18+
settings pages clamp from shared widgets
- queue list-mode, local/downloaded album track lists, favorite
artists, home recent-access, and extension detail sections adopt
wideListInset like the screens fixed earlier
- track metadata content clamped at 720dp, which also tames the
width-derived spectrogram height
- announcement dialog capped at 480dp wide; setup wizard and
tutorial content at 560dp with a 400dp action button
Move hardcoded strings in library settings, announcement link errors,
and unknown track title/artist fallbacks to AppLocalizations. Sync
locale-dependent fallback strings from MainShell.
Introduce AppRemoteConfigService which fetches a platform/version/locale-aware JSON payload from api.zarz.moe/v1/spotiflac-mobile/config and caches it in SharedPreferences. main_shell shows a one-shot announcement dialog (respecting dismissible, CTA, time window and version gates) when no update prompt is pending; dismissed IDs are persisted so each announcement surfaces only once.
Tweaks bundled in: the service health dot loses its blur halo in favour of solid Material 3 tones, and AppInfo gains the remote config endpoint constant. The share listener and SAF migration hook stay synchronous inside the post-frame callback so share-intent URLs never race the network-bound checks.
New unit tests cover the announcement CTA/active-window rules.
