Rahul-Rathour/E-vendor-User-side ? reverse-engineered prompt

Build me a clean e commerce website for customers to browse products and buy things easily.

I want a modern homepage with a simple product listing, category browsing, search, product detail pages, and a cart where people can add, remove, and update items. Make it feel polished on mobile and desktop, with a nice layout, clear buttons, and a smooth shopping flow from browsing to checkout.

Use the existing project structure and make sure it works well as a React style front end. Keep the design user friendly and easy to understand, with placeholder product data if needed. If you need to look up current docs online for anything, go ahead. Also make sure the app is ready to run and build without errors.
