Build me a full ecommerce web app with a clean modern storefront and a simple admin side for managing products and orders. I want users to be able to browse products, search and filter, view product details, add items to cart, sign up and log in, save shipping info, and place orders with a real checkout flow using Braintree. Make sure the app has secure authentication with JWT, a MongoDB backed database, and a responsive design that looks good on desktop and mobile.

Please set it up as a complete working project with a React frontend and a Node and Express backend, and use Tailwind for the styling. I’d like the main pages, auth flow, cart, checkout, order history, and basic product management all wired up so I can run it locally and test it right away. If you need to look up current docs online for any payment or deployment details, go ahead and do that.
