What the model said

I didn't change `0.html`. It's already in good shape, and any edit I made without a goal would just be churn.

It already:
- Centers the circle with `display: grid; place-items: center` and uses `100dvh` so it fits correctly on mobile.
- Scales the circle to fit small screens (`min(400px, 90vmin)`) and keeps the `width`/`height` attributes to prevent layout shift while loading.
- Gives screen readers a name for the circle (`role="img"` plus a linked `<title>`).
- Handles Windows high-contrast mode (`forced-colors`) by switching to the system text colour.
- Includes an inline SVG favicon and the correct `lang`, charset and viewport settings.

The only small gaps are optional:
- **A `<meta name="description">`**, if the page will be public or indexed.
- **A dark-mode version** (black background, white circle), if you want it. It's currently locked to light on purpose via `color-scheme: light`.

Tell me what you'd like from "improve", such as dark mode, animation, interactivity, a different size or colour, or a smaller file, and I'll make the change.
