What the model said
I made `0.html` more robust and accessible without changing how it looks on a normal 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 stray horizontal scrollbar:** the body no longer uses `width: 100vw`, which overflows when a vertical scrollbar is present. - **Correct centring on mobile:** the body height is now `min-height: 100dvh` with a `100vh` fallback, so centring accounts for mobile browser toolbars and content can grow. - **Circle shrinks on small screens:** the SVG is sized `min(400px, 100vmin)` with a 1:1 aspect ratio, so it is no longer clipped on viewports narrower than 400px. - **Screen reader support:** the SVG now has `role="img"` and a `<title>` of "Black circle". - **Minor CSS tidy-ups:** `box-sizing: border-box` is added to the reset and the SVG is `display: block`. ## What I left alone - **Page title:** `<title>ae683f770</title>` and the matching `id` look like generated identifiers, so I kept them. A human-readable title would be better if nothing depends on that value. - **Circle colour:** it still uses the default black fill. "Improve" was open-ended, so I kept to low-risk fixes. If you were after something else, such as colour, animation or dark-mode support, tell me which.
