Build me a simple notes app where I can create, edit, delete, and view my notes in a clean web interface.

I want a frontend and a backend, with the data saved properly so notes still exist after refresh. Keep it easy to use, responsive, and straightforward, with a nice layout for adding a note, seeing all notes, and opening one to make changes. If it makes sense, include basic form validation and simple error handling so it feels solid. Please set it up so I can run the app locally without a lot of extra work, and organize the code in a sensible way between the client and server.

If you need to check current best practices or docs while building it, go ahead and look them up online.
