ShivaMani02/shopnest-ecom-MERN — reverse-engineered prompt

Build me a full stack e commerce app called ShopNest. I want a clean storefront where people can browse products, add items to a cart, sign up or log in with JWT based sessions, manage their personal profile, and see their order history. There should also be an admin area where I can manage products, users, and orders.

Please make it with a React frontend and an Express plus MongoDB backend, with cart state handled properly and protected routes for normal users and admins. Product images should upload to Cloudinary, payments should work with Razorpay using test keys or placeholders, and there should be seed data so I can quickly load demo products and an admin account. If there is already a Postman collection, make sure the API matches it.

Set it up so I can install and run everything from the root folder, and so it can be deployed as a single service on Render with the backend serving the built frontend in production. Look up current docs online if you need to.
