v1666905-lang/Notes-app ? reverse-engineered prompt

Build me a simple full stack notes app where I can create, view, edit, and delete notes, and have everything saved on the backend so it still works after refresh.

I want a clean, easy to use interface with a list of notes on one side or in a simple main view, and a form for adding or editing a note. Make it feel polished and responsive, so it works well on desktop and mobile. Use a modern JavaScript setup for both the frontend and backend, and wire the whole thing together so the app is ready to run locally. If you need to check current docs for any libraries or setup details, go ahead and look them up online.
