what changed from step 047

Nothing. The file is byte-identical to step 047.

What the model said

I reviewed `0.html` and made no changes: it's already in good shape, and anything I'd add would be churn rather than improvement.

I checked it by reading only, not by rendering it in a browser:

| Area | Finding |
|---|---|
| **Document basics** | Doctype, `lang`, charset, viewport, title and description are all present. |
| **Dark mode** | `color-scheme` combined with `fill: currentColor` adapts the circle without any custom colours, and also holds up in forced-colors mode and print. |
| **Sizing** | The `vh`/`dvh` and `vmin`/`dvmin` fallback pairs are ordered correctly, and the `min()` keeps a 1rem gutter on small screens. |
| **Edge clipping** | `overflow: visible` stops the circle's anti-aliased edge being cut off at the viewBox boundary. |
| **Accessibility** | The `main` > `h1` > `svg role="img" aria-label="Circle"` structure gives the page a landmark, a heading and an accessible name. |
| **Favicon** | The inline SVG is correctly URL-encoded and adapts to dark mode. |

"Improve" could mean a few things that are about taste rather than correctness, such as:

- **Visual design:** custom colours, a gradient or some motion.
- **Interactivity:** a response to hover or click.
- **Minification:** stripping the file down to its smallest size.
- **Metadata:** Open Graph tags and `theme-color` for sharing.

If you have one of those in mind, tell me which and I'll make the change.
