Bersaglia un commensale o il Cameriere: ogni lancio alimenta la sua **rabbia (0-100)**. Sopra la soglia, il Cameriere va in **RAGE** e parte la fase di **fuga**: nasconditi, scappa, lancia una sedia… chi viene beccato è **eliminato** e passa in modalità **Spettatore**.

Se vuoi colonne reali, punta due URL in `frontend/audio.ts` → `setPlaylist(lofiUrl, metalUrl)`.\n\n## ⚙️ Configurazione\n\nLa chiave **Gemini** vive nella env var `GEMINI_API_KEY` (mai nel codice). Modelli usati:\n- **Chat** (Cameriere): `gemini-3.5-flash` — attivo.\n- **Immagini** (piatti): `gemini-2.5-flash-image` — richiede **quota** sull'account (limite 0 sul piano free).

Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1.
