what changed from step 046

Nothing. The file is byte-identical to step 046.

What the model said

I reviewed `0.html` and didn't change anything: the file is already in good shape, and I couldn't find an edit that would be a real improvement rather than churn.

## What I checked

| Area | Finding |
|---|---|
| Document basics | Doctype, `lang`, charset, viewport, title and description are all present. |
| Dark mode | `color-scheme` plus `fill: currentColor` makes the circle follow the theme, and this also works in forced-colors mode. |
| Favicon | The inline SVG adapts to dark mode and needs no extra request. |
| Centering | The `100vh` → `100dvh` fallback handles mobile toolbars. |
| Sizing | `min(25rem, 100vmin - 2rem)` keeps the circle on screen in any orientation, with a `dvmin` upgrade. |
| Rendering | `display: block` prevents a baseline gap, and `overflow: visible` stops the edge being clipped where the circle touches the viewBox. |
| Accessibility | There is a `main` landmark, and the `h1` gets its accessible name from `role="img"` and `aria-label`. |

## Changes you could make, depending on the goal

These are matters of taste or depend on where the page is going, so I left them alone:

- **Sharing and deployment:** add a `theme-color` meta tag, Open Graph tags and a canonical URL if this will be hosted publicly.
- **Visual interest:** add a subtle animation, gated behind `prefers-reduced-motion`, or a custom colour via a CSS variable.
- **Smaller file:** the `<main>` and `<h1>` wrappers could go, at the cost of the semantics; I'd keep them.
- **Mobile stability:** swap `dvh` for `svh` if you'd rather the circle not shift as mobile toolbars collapse.

Tell me which direction you mean by "improve" and I'll make the edit.
