111 of 122 top-level src/utils/ files move into 16 topic folders (audio,
cache, cover, share, server, playback, playlist, deviceSync, waveform,
mix, format, export, changelog, ui, perf, componentHelpers). True
singletons with no cluster stay at the utils/ root.
Pure file-move: a path-aware codemod rewrote 539 relative-import
specifiers across 275 files; no logic touched. The hot-path coverage
gate list (.github/frontend-hot-path-files.txt) is updated to the new
paths for the 11 gated utils files — a mechanical consequence of the
move, not a CI change. tsc is green.
Five-cut cluster pulling the dashboard subcards out of NowPlaying.tsx.
1119 → 711 LOC (−408). Each card was already a top-level
React.memo'd block with a clean prop interface, so this is straight
file-per-card extraction with no behaviour change.
Hero — full hero strip: cover image, title, artist/album/year/age
sub, format/codec/sample-rate/bit-depth/duration badges with the
Hi-Res chip, the favourite + Last.fm-love + lyrics action buttons,
play-count line, and the Last.fm track + artist stats rows (with
their per-row `you played N×` highlight). renderStars (5-star
inline indicator) moves inline as a private helper since only Hero
calls it.
ArtistCard — about-this-artist card: optional hero image (filtered
through isRealArtistImage so we don't render the well-known
"2a96…" placeholder), name, sanitized + clamp-with-Read-more bio,
similar-artist chip row. Owns its bioExpanded / bioOverflows state
and the useLayoutEffect that measures overflow.
AlbumCard — from-this-album card: meta line (year / track position /
total duration / play count), sliding-window tracklist anchored on
the current track (top 10 by default, or the 10 ending at the
running track if it's beyond position 10), and the show-all toggle.
TopSongsCard — top-songs-by-artist card: rank-ordered list (max 8),
each row clicks into playerStore via the onPlay callback.
CreditsCard — contributor / song-info card: role-grouped list with
i18n role label lookup (falls back to the raw role string).
NowPlaying drops the now-unused imports (useLayoutEffect, LastfmIcon,
Star, MicVocal, Heart, Headphones, TrendingUp from lucide,
sanitizeHtml + isRealArtistImage + formatTotalDuration from
nowPlayingHelpers) plus the inline renderStars helper. Pure code
move otherwise.
