Findings 5-8 of the dedup audit:
- F5 byte formatters: appUpdaterHelpers.fmtBytes + ZipDownloadOverlay
.formatMB route through the existing formatBytes; a new formatMb
(always-MB) backs playlistDetailHelpers.formatSize, AlbumHeader and
the 4 inline DeviceSyncPreSyncModal expressions. SongInfoModal.format
Size is intentionally left — it uses decimal (1e6) divisors, not 1024.
- F6 sanitizeHtml: extracted to utils/sanitizeHtml.ts; AlbumHeader,
ComposerDetail and the (now-empty, deleted) artistDetailHelpers use it
directly. nowPlayingHelpers keeps its own export but now delegates to
the shared sanitiser and only adds its trailing-link strip on top.
- F7 album duration: BecauseYouLikeRail's formatAlbumDuration drops in
favour of the shared formatHumanHoursMinutes. Behaviour note: total
minutes now floor instead of round (<=1 min display difference,
matches every other caller).
- F8 clock time: extracted to utils/format/formatClockTime.ts;
PlaybackDelayModal + QueueHeader use it (toLocaleTimeString and
Intl.DateTimeFormat produced identical output).
Behaviour preserved except the two explicitly noted divergences (F7
round->floor; F5 appUpdater/Zip now show GB above 1 GB instead of a
large MB number).
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.
