The running webapp explains each module in detail via a\nselectable **Docs** section powered by `frontend/ui/data.ts`.\n\n---\n\n## What This Template Includes\n\n- `index.http.ts` — the only HTTP trigger.\n- Preact SSR + Oat CSS — no build step, no hydration bundle.\n- Tiny JSON API — `/api/health` and `/api/visits`.\n- SQLite — visit counter and cron metadata.\n- Cron — scheduled pulse and maintenance examples.\n- Email — inbound handler and outbound helpers.\n- Blob — small account-scoped storage wrapper.\n- `val.yml.files` — repo-side trigger metadata contract.\n\n---\n\n## Quick Start\n\n```bash\ncd /path/to/uApps\nvt create my-app\ncd vals/my-app\nvt push\nvt url\n```\n\nOpen the URL. The homepage is the module documentation.\n\nBefore changing remote state, use:\n\n```bash\nvt status\nvt push --dry-run\nvt types\n```\n\n---\n\n## HTTP Shape\n\nOnly one file should be an HTTP trigger:\n\n```txt\nindex.http.ts\n```\n\nRoutes:\n\n| Method | Path          | Purpose              |\n| ------ | ------------- | -------------------- |\n| GET    | `/`           | Preact docs app      |\n| GET    | `/api/health` | Runtime health check |\n| GET    | `/api/visits` | SQLite visit count   |\n\nDo not add email, OpenAI, admin, or write routes without auth. Val Town HTTP\nendpoints are public even when the val source is private.\n\n---\n\n## Preact Notes\n\nEvery `.tsx` file containing JSX needs the Val Town JSX pragma at the top:\n\n```tsx\n/** @jsxImportSource https://esm.sh/preact@10.29.1 */\n```\n\nThe pragma selects the JSX runtime. It does not make a file an HTTP trigger.\nTrigger type is Val Town metadata; for new files, `vt` infers it from path words\nsuch as `http`, `cron`, and `email`.\n\nThe UI is intentionally declarative:\n\n```txt\nfrontend/ui/data.ts      # docs/routes/stats data\nfrontend/ui/sections.tsx # maps data to sections\nfrontend/client.ts       # theme, docs tabs, visit count\n```\n\n---\n\n## Trigger Metadata\n\n`val.yml` records the intended Val Town file types:\n\n```yaml\nfiles:\n  index.http.ts: http\n  cron.ts: interval\n  email.ts: email\n```\n\nCheck remote metadata with:\n\n```bash\nvt types\n```\n\nExisting remote files keep sticky metadata. If Val Town shows\n`(script) index.http.ts`, the code may be valid but the file is not an HTTP\ntrigger.\n\n---\n\n## Customize\n\n- Rename the app: edit `APP_NAME` in `backend/shared.ts`.\n- Edit the homepage docs: update `frontend/ui/data.ts`.\n- Add a read-only API route: add a small branch in `index.http.ts`.\n- Add a SQLite table: extend `migrate()` in `backend/db.ts`.\n- Change visibility/org: edit `val.yml`.\n\nKeep files small. Delete modules you do not need.\n\n---\n\n## Key Files\n\n| File                   | Purpose                                             |\n| ---------------------- |
