Build me a full ecommerce site with a customer facing store and a simple backend so people can browse products, search and filter them, see product details, add items to a cart, and place an order.

I want it to feel like a real shopping app, with a clean home page, product pages, cart, and basic user login for saving orders and details. If it makes sense, add a simple admin side for managing products and orders too.

Please wire up the frontend and server so it works end to end, use sensible sample data if needed, and make the app easy to run locally. If you need to check current docs for any libraries or best practices, go ahead and look them up online.
