Without this, the cron and the Ask tab will fail.\n2. The cron runs daily at 06:30 UTC — adjust in interval settings if you want a different time.\n3. **Install on your phone:**\n - Open the val's public URL in Safari (iOS) or Chrome (Android)\n - Tap *Share → Add to Home Screen* (iOS) or *Menu → Install app* (Android)\n - The app opens in standalone mode with the dark masthead\n\n## Files\n\n- `index.html` — The frontend app (vanilla JS, no build step)\n- `manifest.json` — PWA manifest for home-screen install\n- `icon.svg` — App icon (served as `/icon.png` for compatibility)\n- `api.ts` — HTTP handler (serves app, digest, and chat)\n- `cron.ts` — Interval job that builds the daily digest\n- `lib/claude.ts` — Shared Claude API helper\n- `lib/config.ts` — Model, topics, and blob key
