lxfater/inpaint-web ? reverse-engineered prompt

Build me a browser only image editing app that lets people remove unwanted parts of a photo and fill them in naturally, then also upscale images to make them look sharper and cleaner.

I want it to feel simple, like upload an image, paint over the area you want fixed, and let the app generate the repair right in the browser without sending the image to a server. It should also have a way to enhance old or low quality images, with a clear before and after view so users can see the result.

Please make it work well on modern browsers, use the camera and GPU features available in the browser if needed, and keep the interface clean and easy to understand. Add basic edit history so users can undo changes and compare versions. If you need to check current docs or best practices for browser GPU support, go ahead and look them up online.
