What the model said
I made `0.html` more robust without changing how it looks on a desktop screen: it is still a 400px black circle centred on the page. I haven't opened it in a browser to check. ## What changed - **No horizontal overflow:** I removed `width: 100vw` from `body`, which can cause a horizontal scrollbar whenever a vertical scrollbar is present. - **Better mobile centring:** `height: 100vh` is now `min-height: 100dvh`, with `100vh` kept as a fallback. The circle stays centred when mobile browser toolbars show or hide. - **Fits small screens:** the SVG was a fixed 400px, which got clipped on narrow phones. It now uses `width: min(400px, 100vmin)`, so it stays 400px where there is room and shrinks otherwise. - **Screen reader support:** the SVG now has `role="img"` and a `<title>`, so it is announced as "Circle". Hovering over it will also show "Circle" as a tooltip. - **Minor tidy-ups:** I added `box-sizing: border-box` to the reset and `display: block` on the SVG. ## What I left alone - **Page title:** `ae683f770` matches the SVG id, so I assumed it is an intentional identifier. If this page is meant for people, a descriptive title would be better. - **Colours:** the circle still uses the default black fill on a white background.
