simrantripathy-04/mern-ecommerce ? reverse-engineered prompt

Build me a full shopping website where people can sign up, log in, browse products, search and filter by category, add items to a cart, change quantities, and remove things they do not want. I also want address management, a smooth checkout flow, and the ability to place orders. The app should keep track of stock so products update properly when orders are made.

Make it feel modern and responsive so it works well on desktop and mobile. Use a React frontend and a Node and Express backend with MongoDB for the data. Please wire up the API so the frontend can talk to the backend cleanly, and include the basic pages and flows a real ecommerce site needs. If you need to check current docs for anything, go ahead and look them up online.
