joaopedro236/Dailyfoods ? reverse-engineered prompt

Build me a food delivery web app called Dailyfoods, inspired by iFood, with a clean and modern look and a strong mobile friendly experience. I want users to browse restaurants and menus, sign up and log in, and have their information saved through a backend with a database. The app should feel like a real delivery platform, with a smooth frontend, responsive layout, and simple navigation for finding food quickly.

Please connect the frontend to a FastAPI backend, store user and order data in PostgreSQL, and make sure the backend validates the data before saving it. If a user does not have a profile photo, use a default image automatically. Also handle authentication cookies so login stays persistent and the frontend can receive and display the returned user data properly. If you need to look up current docs online while building, go ahead.
