Four-cut cluster. 572 → 471 LOC (−101). Each handler on the page
collapses to a one-line delegate; pure code move otherwise.
runPlaylistSaveMeta — the meta save flow (updatePlaylistMeta then
optional uploadPlaylistCoverArt + getPlaylist refresh + cover toast,
or coverRemoved → null, then metaSaved toast + closes the modal).
Takes the deps separately from the opts object so the call-site
just passes through the modal's payload.
usePlaylistSongSearch — searchOpen + searchQuery driven debounced
search against subsonic. Owns the 350 ms timeout, the filter-out
of songs already in the playlist, and the searching state. Returns
{ searchResults, setSearchResults, searching } so addSong on the
page can still drop a just-added song out of the result list.
usePlaylistSongMutations — addSong / removeSong. removeSong is
trivial (filter + setSongs + savePlaylist with prevCount).
addSong preserves the .main-content scrollTop save / requestAnimationFrame
restore trick + drops the song out of both suggestions and search
results + fires the add toast with playlist name interpolation.
usePlaylistStarRating — handleRate (local override + playerStore
userRatingOverride + setRating API) + handleToggleStar (e.stopPropagation,
local set + playerStore starredOverride + star/unstar API). Reads
starredOverrides / setStarredOverride from playerStore directly so
the page doesn't have to thread them through.
PlaylistDetail drops these direct imports (now consumed in the
hooks/utility): updatePlaylistMeta, uploadPlaylistCoverArt, search,
setRating, star, unstar, showToast, useRef. Pure code move.
