parvans/Multi-Store-Stock-Mgnt ? reverse-engineered prompt

Build me a full stack inventory management app for multiple stores.

I want an admin and shopper login system with protected pages, where admins can create products and stores, update stock, move stock between stores, and see inventory across every store. Shoppers should be able to browse products, stores, stock levels, and quickly filter items that are running low, but they shouldn’t be able to change anything.

Please make it feel like a real modern app, with a clean dashboard style, forms, tables, and clear success or error messages. Use a React frontend and a Node and Express backend with MongoDB, and wire up authentication with JWT and secure password handling. I also want the app seeded with some sample products, stores, and stock so it’s usable right away.

If you need to check current docs for any libraries or best practices, go ahead and look them up online. Build the whole thing so I can run the client and server separately and use it end to end.
