   Unknown routes return raw errors. Add a catch-all route on the frontend for client-side 404s. Consider a Caddy fallback for unrecognized subdomains.

 - **Configurable game settings in multiplayer lobby** `[feature]`
   Game settings (mode, round count, timer duration, target score) are currently hardcoded. The host should be able to configure these when creating a lobby. Settings should be stored in the settings jsonb column on the lobbies table and passed through to the game service at start.
 
+- **Tighten CSP to remove unsafe-inline** `[security]`
+  Current script-src uses 'unsafe-inline' to accommodate framework-injected inline scripts (likely TanStack Router hydration). Tightening this would require nonce-based CSP, which needs server-rendered HTML or a Caddy layer that injects per-request nonces. Not urgent — pragmatic CSP with 'unsafe-inline' is mainstream for SPAs at this scale. Revisit if the app handles more sensitive data or grows a meaningful user base
