 - **Accessibility pass:** global **`:focus-visible`** gold ring (keyboard/controller/switch nav — no pointer required); **reduced-motion** honored app-wide via a `@media (prefers-reduced-motion)` block (kills decorative CSS loops) **and** `<MotionConfig reducedMotion="user">` in `page.tsx` (tames all Framer Motion). Cramped 32px icon buttons (Friends accept/decline/msg/remove, Chat back/send, Room invite/bot/clear) bumped to **44px**. Empty states (Friends/Chat/Notifications) and loading **skeletons** (Leaderboard/Shop) added.
 - **Capacitor Android APK** builds (Myket maven mirror at root `https://maven.myket.ir`; init script pins buildTools 36 + JDK17). See `ANDROID.md`.
 - **CI/CD** (Gitea Actions + Nexus mirror) + Docker stack. See `DEPLOY.md`.
+- **Production prep (bargevasat.ir):** `docker-compose.caddy.yml` + `Caddyfile` (auto-HTTPS: `bargevasat.ir`→web, `api.bargevasat.ir`→server), prod `appsettings`/`ENV_FILE` blocks pointing at the domain, and **`PRODUCTION.md`** (go-live + Cafe Bazaar publish/IAB checklist). Prepare-only — deploy/DNS is manual.
+- **One running game per player:** server `GameManager.StartMatchmaking` re-syncs an existing live room instead of starting a 2nd; client (`game-store.hasActiveMatch()`) guards Home vs-computer + Lobby random/create → resumes the running match + notifies. Clears on forfeit/finish.
+- **Selectable background music:** `santoor` (سنتی) + `playful` (UNO-like), procedural in `sound.ts` (`TRACKS`, `setMusicTrack`, persisted), `sound-store.musicTrack`, picker in Profile → Audio.
+- **100 gated gifts:** purchasable cosmetics LOCKED until a level/rating gate (45 avatars in types.ts, 35 titles + 20 card backs in gamification.ts). Tier (1-5) is encoded in the id (`-t<n>-`); `GIFT_TIERS` is the shared gate table (t1 free → t5 rating 1700). Shop shows locked + requirement; **server enforces generically** by parsing the tier (`ProfileService.GiftGateFor`, mirrors GIFT_TIERS) — no per-item catalog mirror. Items reuse the existing avatar/title/card-back renderers + owned lists.
