copy/v86 ? reverse-engineered prompt

Build me a browser based x86 PC emulator page using this project, with a simple clean interface that lets me boot a few sample operating systems and see the screen, keyboard, mouse, audio, and disk activity working in the browser.

I want a homepage that makes it easy to pick a demo image, start and stop the VM, reset it, and open a full screen view. Please make the default experience feel polished and beginner friendly, with clear loading states, helpful error messages, and basic instructions for what to click if the machine does not boot right away.

If it makes sense, include one or two example profiles like a lightweight Linux boot and a DOS boot, and make sure the build can run locally with a simple serve step. Use the existing docs and examples as a guide, and look up current docs online if you need to.
