Build me a simple MicroNotes app for a class assignment.

I want a small notes website where someone can type a note title and details, save it, and see the saved notes in a recent notes list. Please make the frontend in React and the backend in Node and Express, with the frontend talking to the server through a basic REST API. The server can keep notes in memory for now, so I’m fine with them resetting when the app restarts.

It should load existing notes when the page opens, let me add new ones, and show them right away. A delete note option would be nice too if it fits naturally. Please make the UI clean, responsive, and support a dark theme or dark styling.

Also include a small warmup.js file with a few basic JavaScript practice exercises, since that’s part of the assignment. If you need to check current docs or best practices for setup, go ahead and look them up online.
