C0nw0nk/CoinHive ? reverse-engineered prompt

Build me a simple, friendly demo page for a website that shows a floating mining style widget users can interact with on every page.

I want it to feel clean and easy to customize, with a small panel that can sit in the corner, let the user start, pause, and see the current status, and make it obvious how to change the colors, text, and styling. Keep it lightweight and readable, and make the layout look good on both desktop and mobile.

Please use the existing example in the repo as the guide, and make the finished page easy for someone else to copy into their own site. If anything needs current setup details, look up the latest docs online. Also include a simple sample page so I can see how it works right away.
