* refactor(artists): extract helpers + constants
Pull ALL_SENTINEL / ALPHABET / ARTIST_LIST_* row-height estimates,
the ArtistListFlatRow union, CTP_COLORS palette, and the deterministic
nameColor / nameInitial helpers into utils/artistsHelpers.ts.
Artists.tsx: 520 → 496 LOC.
* refactor(artists): extract ArtistAvatars subcomponents
Pull ArtistCardAvatar (300px, grid view) and ArtistRowAvatar (64px, list
view) into components/artists/ArtistAvatars.tsx. Both fall back to a
hashed-Catppuccin monogram when artist images are off or no cover art
is available.
Artists.tsx: 496 → 436 LOC.
* refactor(artists): extract useArtistsFiltering hook
Bundle the letter/text/star filter pipeline, visible-slice memo,
group-by-letter, and the virtualizer flat-rows list into
hooks/useArtistsFiltering.ts. List-view-only outputs short-circuit when
grid view is active.
Artists.tsx: 436 → 386 LOC.
* refactor(artists): extract useArtistsInfiniteScroll hook
Bundle visibleCount + loadingMore state, the sentinel
IntersectionObserver, loadMore callback, and the filter-change reset
into hooks/useArtistsInfiniteScroll.ts. The observer no longer takes
hasMore — the sentinel element only mounts while there is more data,
so the observer attaches/detaches naturally with it.
Artists.tsx: 386 → 370 LOC.
* refactor(artists): extract ArtistsGridView + ArtistsListView
Move the grid card layout to components/artists/ArtistsGridView.tsx and
the dual-path list layout (non-virtualized fallback + virtualized stream)
to components/artists/ArtistsListView.tsx. Both paths now share an
internal ArtistListRow component so click + context-menu behaviour is
identical regardless of which renderer is active.
Artists.tsx: 370 → 233 LOC.
