what changed from step 034
Nothing. The file is byte-identical to step 034.
What the model said
I didn't change `0.html` because it's already in good shape and I couldn't find anything that would clearly make it better. It's a single black circle, centered on the page, and it already: - **Resizes with the screen:** it's never more than 400px wide or more than 90% of the screen's shorter side. - **Stays centered on mobile:** it uses `100dvh`, so it stays centered when the browser's address bar shows or hides. - **Works with screen readers:** it has `role="img"` and a `<title>` that screen readers announce. - **Works in Windows high-contrast mode:** there's a rule for that mode (`forced-colors`) so the circle stays visible. - **Has a matching tab icon:** a small black circle is built into the file, so it needs no extra request. Anything more would be a matter of taste, not a fix: 1. **Dark mode:** show a white circle on a black page when the system uses dark mode. 2. **Less code:** replace the SVG with a `<div>` styled with `border-radius: 50%`. 3. **A description:** add a `<meta name="description">` tag for search results and link previews. If you had a specific goal in mind, like different behaviour, a different look, animation or smaller file size, tell me and I'll make the change.
