Build me a modern ecommerce app with a clean responsive storefront, where people can browse products, search and filter by category, price, rating, and sort them easily. I want product detail pages, a cart, and a checkout flow with shipping, payment options, and order confirmation.

Please add user accounts too, so people can register, log in, stay signed in, view their profile, and see their past orders and order details. Admin users should be able to manage products, users, and order delivery status.

I also want a floating AI shopping assistant on every page that can answer questions in plain language, recommend products, compare items, help with policies and shipping, and let signed in users ask about their orders. If the AI service is unavailable, it should still give useful answers using the store data.

Use a polished glassy style, make it feel modern, and include sample data so the store works right away.
