0CHARANGURU/e-commerce ? reverse-engineered prompt

Build me a simple e commerce app with a frontend and a backend.

I want users to be able to browse products, view a product page, add items to a cart, and go through a basic checkout flow. Make it feel clean and easy to use on desktop and mobile. Set up the backend so it can store and serve product data, and keep the frontend talking to it properly.

Please make the project ready to run from the start, with sensible folder structure, clear setup steps, and working pages instead of placeholders. If you need current docs for anything, look them up online first.
