sreejithKpy/ecommerce-frontend ? reverse-engineered prompt

Build me a responsive e commerce frontend that feels like a real online store on desktop and mobile.

I want shoppers to be able to browse products, open a product detail page, add items to a cart, update quantities, and move around the site smoothly with page navigation. Use a clean modern layout with a home page, product listing, cart view, and a simple checkout style flow, even if it is mostly frontend only for now. Make sure the app fetches product data from an API, handles loading and error states nicely, and keeps cart state working across the site. It should look polished, be easy to use, and feel fast. If you need to check current docs for any setup details, go ahead and look them up online.
