DB - Added 7 user pref columns; vibration is now per-channel (vibrationEnabledOrder + vibrationEnabledMeeting). Defaults: ding/chime sounds, vibration on, mute off, volume 70. API - PATCH /auth/me/notification-preferences (requireAuth, whitelisted partial update, integer guard for volume). buildAuthUser exposes all new fields. - OpenAPI spec updated; orval client + zod regenerated. Frontend - Static sound library: 8 short WAV assets under public/sounds/ + manifest (notification-sound-manifest.ts) mapping id -> labelKey -> URL. - HTMLAudio-based player (notification-sounds.ts) with throttle, unlock, cache, and AUTOPLAY_BLOCKED_EVENT dispatch when play is denied pre-gesture. - Settings popover: global mute, volume, slot tabs (orders/meetings) with per-channel sound + per-channel vibration + per-channel toggle, sound list with one-tap previews. Concurrency-safe optimistic updates (monotonic seq counter). RTL-correct toggle knob transforms. - QuickMuteButton: one-tap topbar mute control (Volume2/VolumeX) with confirmation toast. - useAudioUnlock: unlocks audio on first interaction. - useAutoplayHint: toasts a localized "click anywhere to enable" hint when the player reports a blocked play attempt. - Socket hook plays the right per-channel sound + vibration on notification_created (orders, executive_meeting) when the tab is hidden. - UpcomingMeetingAlert: plays meeting reminder once per new eligible meeting (deduped by meetingId, survives 30s polling refetches). - AR/EN translations added. Pre-existing TS errors in executive-meetings.ts (font_settings) and pre-existing test workflow failures are unrelated.
