sam-maass/qr-menu ? reverse-engineered prompt

Build me a simple QR menu web app for a restaurant.

I want customers to scan a QR code and open a clean mobile friendly menu page that shows categories, items, prices, and descriptions. It should be easy to update the menu from the backend, and the frontend should look good on phones.

Please set up the full project so it runs locally and with Docker too. I’d like a basic admin or backend area to manage menu items, and the public menu page should load fast and be easy to browse.

If anything is unclear, make sensible choices and keep it simple. Feel free to look up current docs online if you need to.
