NartanNaik/Unpack ? reverse-engineered prompt

Build me a simple full stack web app called Unpack with a clean frontend and a working backend.

I want it to feel polished and easy to use, with a modern interface that makes it simple to add, view, update, and remove items. Please wire up the frontend and backend so everything actually works together, and include sensible empty states, loading states, and basic error handling.

Make it look good on both desktop and mobile, and keep the code organized so it would be easy for me to extend later. If you need to look up current docs online for anything, go ahead and do that.
