zaki98765/book-store ? reverse-engineered prompt

Build me a full online bookstore app where people can sign up, log in, browse books, view book details, add items to a cart, and place orders.

I also want an admin area where I can add, edit, and remove books, see orders, and manage the store from one place. Make it feel clean and easy to use on desktop and mobile, with simple navigation for shopping and a separate section for admin tasks.

Use a modern full stack setup and wire up the frontend to a backend so the main flows actually work, including authentication, cart handling, and order creation. If you need to check the latest docs for anything, go ahead and look them up online. Please make the app polished enough that it feels like a real bookstore people could use right away.
