What the model said
I made `0.html` more robust without changing how it looks: it is still a black 400px circle centred on the page. I haven't opened it in a browser to check. ## What changed - **No stray horizontal scrollbar:** the body used `width: 100vw; height: 100vh`, which can overflow when a scrollbar is present. It now uses `min-height: 100vh`, with `100dvh` so it fits properly under mobile browser toolbars. - **Scales on small screens:** the circle was fixed at 400×400px and would be clipped on a narrow viewport. It now shrinks to fit (`width: min(400px, 100vmin)`) and stays square. - **Screen-reader label:** the SVG now has `role="img"` and a `<title>`, so it is announced as "Circle" instead of being skipped or read ambiguously. - **Small CSS cleanups:** `box-sizing: border-box` is added to the reset, and the SVG is `display: block` to avoid inline whitespace below it. ## What I left alone - **Page title and id:** `ae683f770` looks like a generated identifier, so I kept it in both places. A descriptive `<title>` would be better if this page is user-facing. - **Colours:** the circle still uses the default black fill on a white background, with no dark-mode handling. "Circle" is a placeholder label; if the shape means something specific (a logo, a status dot), swap in that wording.
