segjay/UrbancartMERN ? reverse-engineered prompt

Build me a simple Urbancart style shopping app with a backend and a frontend.

I want users to be able to browse products, add items to a cart, and place an order in a clean, modern interface. It should feel like a real e commerce app, with a good looking homepage, product listing, product details, cart, and basic checkout flow. Use the existing backend and frontend setup in the repo, and wire the two together so the data actually comes from the server.

Please make the app easy to run locally, handle loading and empty states nicely, and keep the code organized so it would be easy to add login, admin tools, and more features later. If you need to check current docs or best practices for anything, feel free to look them up online.
