MaximeRivest/riddle ? reverse-engineered prompt

Build me a reMarkable Paper Pro app that feels like Tom Riddle’s diary. I want to write on the page with the pen, then after a short pause my ink should fade into the paper, the app should think for a moment, and a reply should write itself back in a flowing handwritten style, stroke by stroke, then slowly fade away. No normal chat UI, no keyboard, just a magical ink on paper feel.

It should remember past pages on the device so I can ask things like what do you remember or show me the page about the garden, and it should replay my old handwriting and the old reply in a faded way. Support erasing with the marker, a big question mark to show help, and the takeover style full screen mode for the Paper Pro, with a safe way to exit. Make it work with an OpenAI compatible vision model using an API key, and keep the setup friendly for someone installing through remagic or AppLoad. Look up any current docs you need.
