Consolidated fix wave from the final whole-branch review of guest mode.
- FIX 1 (critical): gate /api/favorites mount with requireNotGuest — the
router keys off req.user.id (shared __guest__ principal), so guests could
read/write a shared favorites bucket. Added focused guest-deny tests.
- FIX 2: gate GET /api/auth/status and /api/auth/qrcode/status with
requireNotGuest so config reads no longer leak to guests.
- FIX 3: requireAuthInline in createSessionRouter now rejects guest sessions
with 401 once guest mode is disabled (mirrors createRequireAuth), so /me
stops returning guest data after an admin disables the feature.
- FIX 4: Login guest button now sits BELOW the card (auth-page flex-direction
column + guest-btn width 360px) instead of beside it.
- FIX 5: mobile mini-player transport buttons in App.vue are now per-button
gated for guests (prev/play/next/mode/volume), mirroring Player.vue.
- FIX 6: refreshed stale "gated on player.control" seek comments in Player.vue
and relabeled the now-stale quality-GET test.
npm test: 354/354 pass. npm run build: tsc + vue-tsc + vite all green.
