Four-cut cluster opening the Playlists refactor. 1039 → 763 LOC
(−276).
playlistsSmart — full smart-playlist module: SMART_PREFIX /
LIMIT_MAX / YEAR_MIN / YEAR_MAX constants, GenreMode / YearMode /
SmartFilters / PendingSmartPlaylist / NdSmartRuleNode types,
defaultSmartFilters seed, clampYear / isSmartPlaylistName /
displayPlaylistName / asRecord helpers, parseSmartRulesToFilters
(the Navidrome JSON rule walker), and buildSmartRulesPayload (the
reverse — page-state → Navidrome JSON). The payload builder
becomes parameterized on the filters object so it lives outside
the component.
PlaylistCoverImages — two tiny CachedImage wrappers
(PlaylistSmartCoverCell for the 200 px collage cells,
PlaylistCardMainCover for the 256 px main card cover).
useSmartCoverCollage — replaces the inline useEffect that builds
the 2×2 cover collage for each smart playlist (pulls playlist
tracks, filters to active library scope, collects up to four
unique cover-art ids). Returns the per-playlist id map and
re-fetches on playlist list change or library filter version bump.
usePlaylistsLibraryScopeCounts — replaces the inline useEffect
that recomputes per-playlist song count + total duration under
the current library scope. Chunked into batches of four parallel
fetches.
Playlists drops the inline definitions; pure code move otherwise.
