vstefan699-ai/MERN_Tut3 ? reverse-engineered prompt

Build me a simple full stack app with a client and a server, something like a basic MERN starter project.

I want the frontend to let a user view, add, edit, and delete records, and the backend to save that data in a database through a clean API. Make it feel polished and easy to use, with basic form validation, loading states, and simple error messages.

Use the existing client and server folders, wire them together, and set it up so I can run the app locally without much fuss. If you need to check current docs for any setup details, go ahead and look them up. Also include clear README steps for installing, starting both sides, and any environment variables I need.
