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.
The 186-LOC default export shrinks to a thin window-kind switch with
shared document-attribute hooks. The mini-player tree and the main-app
tree each move into their own module under src/app/.
- src/app/MiniPlayerApp.tsx (48 LOC):
DragDropProvider + MiniPlayer + cross-window storage sync
- src/app/MainApp.tsx (129 LOC):
BrowserRouter + Routes + main-only lifecycle hooks
(audio listeners, hot cache, global shortcuts, mini-player
bridge, easter egg, scrollbar auto-hide)
AppShell + RequireAuth + TauriEventBridge are now named exports from
App.tsx so MainApp can compose them; Phase C/D will extract those into
their own modules.
App.tsx: 1453 -> 1308 LOC. Behaviour-preserving.
