Build me a full stack jewellery shopping website for a one gram jewellery store.

I want customers to be able to browse products, view details, add items to a cart, and sign up or log in so they can use the site properly. It should feel clean, modern, and easy to use on phones and desktops, with a simple storefront style that fits jewellery. Please also include an admin side for adding, editing, and managing products, and make sure product images are handled nicely.

Use a React front end with a Node and Express backend, and connect it to MongoDB for storing users, products, and cart related data. If it helps, use current docs online for anything that needs setup or best practice details. Keep the whole thing polished and ready to run, with sensible folder structure and basic authentication flow working end to end.
