siampathan/E-commerce ? reverse-engineered prompt

Build me a full stack e commerce app with a customer side site and an admin area.

On the customer side, I want people to be able to browse products, see product details, search and filter items, add things to a cart, sign up or log in, and place orders. It should feel clean and modern, with a simple checkout flow and a place to view past orders.

On the admin side, I want a dashboard where I can add, edit, and delete products, see all orders, update order status, and manage the store easily.

Use a typical MERN style setup for the whole thing, and make it work smoothly from frontend to backend with real data storage. If you need to, look up current docs online for any libraries or best practices. Please build it so it is usable and organized, and include sensible default styling so it looks like a real store right away.
