The full-bleed cover made the Hero flight from square list thumbnails
morph into a fullscreen rect and back. The header now blurs the cover
as a backdrop and shows a centered rounded square (album header layout),
so the flight stays square end to end.
The local/downloaded album screens had drifted copies of the album
header, selection bottom bar, disc chip, batch convert/ReplayGain trio,
and assorted small helpers. All now delegate to the shared widgets, with
the online album screen's design as the reference, and both album screens
run batch actions through the queue_tab engine via UnifiedLibraryItem
(strict-superset implementation covering both DB writebacks and SAF
paths). Also folds the remaining per-screen helper copies (cover URL,
error card, byte/clock formatting, readPositiveInt) into their shared
homes.
Intentional deltas: selection-bar strings follow queue_tab's l10n keys,
both providers reload after a conversion, and audio-analysis durations
round instead of floor.
Service ids ('deezer', 'tidal', 'qobuz', 'spotify', 'amazon', 'local')
were compared as raw string literals in every dispatch chain. Introduce
MusicServices constants and use them at the comparison/switch sites so
a typo becomes a compile error instead of a silently dead branch.
track_metadata_screen.dart was 5,470 lines, most of it one State class
mixing five surfaces. Move four cohesive method clusters into private
extensions on _TrackMetadataScreenState in new part files: header/info
cards, lyrics + save/re-enrich flows, audio conversion + CUE split, and
file actions. Same library, so private state access is unchanged;
setState goes through a _setState forwarder as in queue_tab. The screen
file is now 1,575 lines.
