See [`_specs/astryx-template.md`](../../_specs/astryx-template.md) for the migration\nhistory, version pins, and the two Deno SSR bugs that had to be worked around.\n\n`_template` is excluded from main-branch deployment because its directory starts with `_`.\n\nSince every Val Town HTTP val is browsable source, the deployed copy of this App is readable at\n`https://www.val.town/x///code/` — e.g.\n`https://www.val.town/x/pikachu/Quickstart-Full-Stack/code/backend/auth.ts`. In-app \"view source\"\nlinks use this same pattern (see `VAL_TOWN_USERNAME` below).\n\n---\n\n## Create a Val\n\nFrom any directory after sourcing the uApps shell plugin:\n\n```bash\nvtx new my-app\ncd vals/my-app\nvtx status\nvtx push --dry-run\nvtx push\nvtx url\n```\n\n`vtx new` copies the template, replaces the application name and account-scoped Blob prefix, writes\nthe new `val.yml` name, and links the new remote val. Existing destinations are refused.\n\n## Application Shape\n\nThe HTTP entry wraps the app in Val Town OAuth, routes `/api/*` through typed auth boundaries, and\nrenders the selected SSR page for every other path.\n\nPages — read in this order the first time:\n\n- `/` — what this App is, who it's for, and where to go next.\n- `/anatomy` — block diagram of Val Town's infra layer, this App's routing, and its core stack.\n- `/http` — HTTP routes and live request demos.\n- `/sqlite` — visit log and admin controls.\n- `/cron` — scheduled task history.\n- `/email` — inbound and outbound email examples.\n- `/blob` — token-protected Blob read/write/list demo.\n- `/ui` — Astryx theming explainer + component showcase.\n\nAPI routes:\n\n| Method | Path | Access |\n| ------ | ---------------------- | ---------------------- |\n| `GET` | `/api/health` | Public |\n| `GET` | `/api/me` | Public session context |\n| `GET` | `/api/visits` | Public |\n| `POST` | `/api/prune-visits` | Admin |\n| `GET` | `/api/cron-runs` | Public |\n| `GET` | `/api/blob-keys` | Demo token |\n| `POST` | `/api/blob-write` | Demo token |\n| `GET` | `/api/blob-read` | Demo token |\n| `GET` | `/api/admin/users` | Super-admin |\n| `POST` | `/api/admin/set-admin` | Super-admin |\n\n## Runtime Configuration\n\nSet these in the created val's Val Town environment UI, never in Git or GitHub Actions:\n\n| Variable | Kind | Purpose |\n| ------------------- | -------- | ------------------------------------------------------------------------- |\n| `APP_NAME` | Optional | Display name override |\n| `VAL_TOWN_USERNAME` | Optional | Your Val Town username — powers \"view source\" links on `/` and `/anatomy` |\n| `DAILY_HOUR_UTC` | Optional | Daily task hour, `0`–`23` UTC |\n| `BLOB_DEMO_TOKEN` | Optional | Enables public Blob demo routes |\n| `AUTH_SUPER_ADMINS` | Optional | Comma-separated Val Town usernames |\n\nThe repository-level `VAL_TOWN_API_KEY` secret is only for CI deployment. See the root\n[`README.md`](../../README.md#cicd).\n\n## Trigger Contract\n\n`val.yml.files` declares the intended remote types:\n\n```yaml\nfiles:\n index.http.ts: http\n cron.ts: interval\n email.ts: email\n```\n\nRun `vtx types` after linking. Use `vtx apply-types` only when deliberately repairing remote trigger\nmetadata.\n\n## Architecture\n\n- `index.http.ts` — HTTP composition root: per-route SSR page serving, `GET /theme` (zero-JS mode\n switch), and the API route table.\n- `backend/auth.ts` — OAuth context and role enforcement. Auth types use `Cxt` (e.g. `UserCxt`,\n `RouteCxt`) — the more common short form for \"context\" — not `Ctx`.\n- `backend/handlers.ts` — focused API handlers.\n- `backend/db.ts` — retryable migration, visits, Cron runs, and users.\n- `backend/storage.ts` — val-namespaced account Blob access.\n- `frontend/app.tsx` — React SSR composition root; dispatches one page per request via a `PAGES` map\n (no client-side router — navigation is real ``).\n- `frontend/astryx/` — pinned Astryx component barrel (`components.ts`), the RAF/CAF SSR shim\n (`ssr-shims.ts`), and the side-nav/theme-form shell (`shell.tsx`).\n- `frontend/pages/` — one file per route, composed from Astryx components. `home.tsx` and\n `page-anatomy.tsx` are the tutorial's two \"read first\" pages; the rest are live feature demos.\n- `frontend/pages/kit.tsx` — shared page pieces, including `SourceLink`/`SourceLinkList` (the \"view\n source\" links, degrade gracefully when `VAL_TOWN_USERNAME` is unset).\n- `frontend/client.ts` — non-hydrated demo API wiring only (no router, no theme JS — both are\n server-driven).\n\nThis template does not hydrate React: `client.ts` is inlined via `dangerouslySetInnerHTML` and only\ndoes `fetch` + `textContent` DOM updates by element `id`. Components that need hydration (Astryx's\n`CodeBlock` copy button, `TextInput`/`Field`) are either disabled or avoided — see\n[`_specs/astryx-template.md`](../../_specs/astryx-template.md) for the full list and reasoning.\n\n## Key Files\n\n| Path | Purpose |\n| --------------------------------- | -------------------------------------------- |\n| `index.http.ts` | HTTP, page routing, `GET
