Three classes:
1. album_cover_cache.dart docstring used <applicationCacheDirectory>
and <albumId> which the analyzer reads as unintended HTML. Wrapped
the path in backticks and used {} placeholders.
2. settings AppearanceSection used RadioListTile.groupValue + onChanged,
deprecated in Flutter 3.32+. Wrapped the radios in a RadioGroup
ancestor (the new API) so individual tiles only declare value +
activeColor. Test updated to read groupValue off the RadioGroup
ancestor.
3. theme_extension.dart factories built FabledSwordTheme(...) without
const, even though all args are static const tokens. Added const to
the outer constructor calls in both .dark() and .light() — this
propagates const to the inner TextStyle(...) calls automatically.

Fetches album cover bytes via the authenticated dio and writes to
<applicationCacheDirectory>/album_covers/<albumId>.jpg. Returns the
local path so MediaItem.artUri can point at a file:// URI — Android's
MediaSession framework fetches artUri itself without our Bearer
header, so a pre-fetched local file is the workaround.
Concurrent callers for the same albumId dedupe to one fetch via an
in-flight Future map. Any failure (network / 4xx / 5xx / disk full /
empty id) returns null without throwing — playback continues with
the system's generic music icon, same UX as today.
No eviction — covers are tiny, OS clears cache when space is tight.
