Prince-verma56/e-commerce-clothing-brand- — reverse-engineered prompt

Build me a modern online store for a clothing brand using this existing Next.js project. I want it to feel like a real fashion site, with a clean homepage, nice product sections, category browsing, product detail pages, a shopping cart, and a simple checkout flow that looks finished even if payments are just mocked for now.

Please make it responsive for mobile and desktop, with polished styling, good spacing, product cards, image placeholders or sample clothing images, prices, sizes, colors, quantity controls, and clear calls to action. Add basic state so customers can add items to the cart, update quantities, remove items, and see the total.

Keep the code organized in the existing app structure and use what’s already installed instead of adding unnecessary complexity. If anything is unclear, make sensible choices for a small clothing brand. Look up current docs online if you need to, then make the app run locally without errors.
