 ## Worker Code Patterns (backend/src/worker.ts)
 
-The Worker backend only serves JSON APIs. **No npm packages allowed** (no hono, express, etc.). Write routes manually:
+In this template, the Worker backend is used primarily for JSON APIs. Prefer standard Web APIs and simple manual routing by default. Worker-compatible libraries can be added when needed, but the default template does not rely on extra frameworks. Avoid packages that depend on unsupported Node.js runtime features.

 ## Important Notes
 
 - `pinme.toml`, `backend/wrangler.toml`, `frontend/.env` are auto-generated — do not modify
-- Frontend API URL is obtained via `VITE_WORKER_URL` env var — do not hardcode
+- Frontend API URL is obtained via `VITE_API_URL` env var — do not hardcode
 - Passwords, tokens, and API keys must be stored in secrets, never in config files
