shwetankg07/shopkart ? reverse-engineered prompt

Build me a small online store called ShopKart that lets people sign up, log in, browse products, search and filter the catalogue, save items to a wishlist, add them to a cart, and place an order. I want checkout to use Razorpay test mode, with the order only marked paid after payment is verified, and then the stock should update and the cart should clear. Users should also be able to view their past orders and order details.

Please include an admin area too, where an admin can add, edit, and delete products, upload product photos to Cloudinary, and change order status from placed to delivered. Make it feel polished and modern, with smooth motion and a nice shopping experience. Use a React frontend and a Node and Express backend with MongoDB, and make sure login stays secure with a cookie based session. If you need to check current docs for Razorpay or Cloudinary, look them up online.
