what changed from step 015

Nothing. The file is byte-identical to step 015.

What the model said

I reviewed `0.html` and didn't change anything: I couldn't find an edit that would be a real improvement rather than churn. I read the file but did not render it in a browser.

It already handles the things I'd normally fix:

- **Layout:** the circle is centred with grid, sized with `min(400px, 100dvmin - 2rem)`, and has `vh`/`vmin` fallbacks for older browsers.
- **Dark mode:** `color-scheme` plus `fill: currentColor` flips the circle automatically, and the favicon has its own `prefers-color-scheme` rule.
- **Accessibility:** `lang`, a `<main>` landmark, and `role="img"` with `aria-label` on the SVG are all there.
- **Rendering details:** `display: block` avoids the inline baseline gap, and `overflow: visible` prevents the edge of the circle being clipped.

The only candidates I found are judgment calls, not fixes:

| Possible change | Trade-off |
|---|---|
| Use `100svh` instead of `100dvh` | Stops the circle shifting when mobile toolbars collapse, but it's no longer centred in the expanded viewport. |
| Replace `aria-label` with an SVG `<title>` | Same accessibility, but adds a hover tooltip. |
| Shrink the coordinates (`viewBox="0 0 2 2"`, `r="1"`) | A few bytes smaller, identical rendering. |

If you had a different kind of improvement in mind (visual styling, animation, interactivity, or more content), tell me which and I'll make it.
