syedfaraz1/three-tier-mern-app ? reverse-engineered prompt

Build me a simple three tier MERN app that shows the full flow from a front end, to an API, to a database. I want a clean app where a user can add, view, update, and delete a few records from the browser, with the data saved properly and loaded back after refresh. Please set up the project so it runs locally without a lot of extra work, and make the UI simple and easy to use.

Keep it straightforward and make sure the pieces are wired together clearly, with the client talking to the server and the server talking to the database. If anything needs current setup details or best practices, look up the latest docs online and use them. I mostly want something I can open, run, and understand as a working example of a basic full stack app.
