What the model said
I didn't change anything in `0.html`. It's already in good shape, and I couldn't find a real problem to fix: - **Markup:** valid HTML5, with `lang`, a viewport tag and a `<main>` element. - **Accessibility:** the SVG has `role="img"` and a `<title>` linked by `aria-labelledby`. There's also a Windows high-contrast override (`forced-colors`) so the circle stays visible. - **Layout:** the circle is centred with `100dvh`, so mobile browser toolbars don't push it off-centre. It scales with `min(400px, 90vmin)` and keeps its shape because of the `viewBox`. - **Other details:** it has an inline SVG favicon, so there's no 404 for `favicon.ico`, and `color-scheme` is set explicitly. The only changes left would be a matter of taste, like adding a `<meta name="description">` or supporting dark mode. Tell me what you're after (visual changes, animation, dark mode, making the size or colour configurable, something else) and I'll make it.
