Aditya73918/Bites-app ? reverse-engineered prompt

Build me a food ordering app called Bites that feels like a polished demo but actually works end to end.

I want users to be able to sign up, log in, browse restaurants and dishes, search and filter by category, add items to a cart, and check out with a saved delivery address and payment method. After checkout, the order should show up in an orders page where people can track it, cancel it if it is still pending, or reorder it. Add a profile page where users can edit their name, email, and phone, plus a dark and light theme toggle and a few small notifications or usage stats. Keep the experience personalized so each signed in user has their own cart, orders, and saved info. Use a React frontend with a Node and Express backend and MongoDB for storage. Make sure authentication is secure with JWTs, and if you need anything unclear, look up current docs online and keep the app simple and clean.
