Build me a simple full stack ecommerce app where people can browse products, see product details, add items to a cart, and place an order. I want a clean frontend for shoppers and a backend that handles products, users, orders, and basic data flow between the two.

Please make it feel like a real online store, with pages for home, product listing, product details, cart, login, signup, and a basic checkout flow. If it makes sense, include a simple admin side for adding and managing products too. Keep the design modern and easy to use on desktop and mobile.

Use the existing client and server setup in this repo, and wire everything together so it actually works end to end. If you need to look up current docs or best practices while building it, go ahead.
