Muhammad-Seifeldin/Nova-Cart-Next.JS — reverse-engineered prompt

Build me a polished shopping cart website called Nova Cart using this Next.js starter. I want it to feel like a modern online store, with a nice homepage, product cards, categories, search or filtering if it’s simple to add, a product details view, and a cart where people can add items, change quantities, remove items, and see the total update.

Keep it frontend only for now, using sample products in the project so it works right away without a database. Make it responsive so it looks good on desktop and phone, and give it a clean premium style with reusable components. Add a simple checkout page or checkout summary, but it can just be a demo form with no real payments.

Please wire everything up so I can run it with npm run dev and click through the whole flow. If you need current Next.js docs, look them up online.
