subham23-cyber/MERNSTACK-TASK-4 ? reverse-engineered prompt

Build me a simple full stack MERN app with a separate frontend and backend.

I want a clean app that lets a user do the basic create, read, update, and delete flow for one simple kind of record, with a nice interface on the front and a working API on the back. Make it easy to run locally, keep the code organized, and wire the frontend to the backend so everything actually works together. If you need to check current best practices or docs for anything, feel free to look them up online.

Please also make it look polished enough to demo, handle loading and error states, and include the usual setup so I can start it and test it without much extra work.
