SawyerHood/draw-a-ui ? reverse-engineered prompt

Build me a simple web app where I can draw a rough wireframe on a canvas, then click a button and get back a clean HTML version of it. I want the drawing area to feel easy and fast, like a whiteboard for mockups, and after I submit it, the app should send the sketch to an AI vision model and turn it into a single HTML page using Tailwind styling.

Please make the flow feel polished, with a clear place to draw, a button to generate the result, and a preview or output area so I can copy the HTML. It should work as a fun demo rather than a full product, so keep it straightforward. If you need current setup details or API usage, look up the latest docs online.
