What the model said

I left `0.html` unchanged because it's already in good shape. It's a small, valid page that shows a centered black circle, and it covers the usual details:

- **Layout:** the circle stays centered on any screen size, including mobile browsers where the address bar changes the page height.
- **Sizing:** it scales down to fit small screens but never grows past 400px.
- **Accessibility:** screen readers announce it as an image called "Black circle", and it stays visible in Windows high-contrast mode.
- **Extras:** it has a matching circle as the browser-tab icon, and the page stays light even when the user prefers dark mode.

Changing things just to change them wouldn't make it better. If you tell me what you're after, I'll make that change, for example:

- a dark-mode version (white circle on black)
- animation or hover effects
- a size or color you can adjust
- turning it into something more than a single circle
