217
220- Hono is the recommended API framework
221- Main entry point should be `backend/index.ts`
222- **Static asset serving:** Use the utility functions to read and serve project files:
223  ```ts
224  import { readFile, serveFile } from "https://esm.town/v/std/utils@85-main/index.ts";
254- Run migrations on startup or comment out for performance
255- Change table names when modifying schemas rather than altering
256- Export clear query functions with proper TypeScript typing
