GR4Yxx/Neuron ? reverse-engineered prompt

Build me a browser app where I can draw handwritten digits and the model recognizes them in real time as I draw. I want to see the network working too, with animated activations moving through the layers, a live prediction score, and a little history of recent guesses.

If it gets a digit wrong, I want a simple way to teach it the correct answer and have it learn from my handwriting right away. It should also have a “dream” mode where I click a digit and the app shows the network’s own imagined version of that number forming on the canvas.

Please make it all run in the browser with no backend, and include a clean modern UI. If you need current docs for anything, look them up online.
