What the model said
I made robustness and accessibility improvements to `0.html` while keeping the look the same: a black 400px circle centred on the page. I haven't opened it in a browser to check. ## What changed - **No horizontal scrollbar:** removed `width: 100vw` from `body`, which overflows whenever a vertical scrollbar is present. - **Better mobile centring:** `height: 100vh` is now `min-height: 100dvh`, with `100vh` kept as a fallback. The circle centres in the visible area when mobile browser toolbars show, and the page can grow if content is added. - **Scales on small screens:** the SVG was fixed at 400×400px and got clipped on narrow viewports. It is now `width: min(400px, 100vmin)` with `aspect-ratio: 1`, so it shrinks to fit. - **Accessible:** the SVG has `role="img"` and a `<title>`, so screen readers announce it as "Circle". Hovering over it will now show a "Circle" tooltip. - **Minor hygiene:** added `box-sizing: border-box` to the reset and `display: block` on the SVG. ## Left alone - **Page title and id:** I kept `ae683f770` as both, in case something references them. If this is a user-facing page, a descriptive `<title>` would be better. - **Dark mode:** the circle uses the default black fill on the default white background. I didn't add dark-mode support because that changes the design.
