AyoubAZ-0/Tp-eCommerce — reverse-engineered prompt

Build me a simple online shop using the existing Symfony project. I want visitors to be able to browse products, open a product page, add items to a cart, update quantities, remove items, and see a clear checkout summary before confirming an order.

Please make it feel like a real small store, with clean Twig pages, a homepage, product listing, product details, cart page, and basic order confirmation. Add the database entities and migrations needed for products, cart or orders, and include some sample products so I can run it right away and see the site working.

Keep the design simple but polished, responsive, and easy to understand. Use the existing folders and Symfony setup instead of starting over. If there are missing details, make sensible basic choices. Also make sure the project can be started locally with the current compose or Symfony setup, and add a few basic tests for the main shopping flow.
