What the model said
I tidied up `0.html` 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 has `width: 100vw`, which overflows whenever a vertical scrollbar is present. - **Better mobile height:** the body uses `min-height: 100dvh` (with a `100vh` fallback), so the circle stays centred when mobile browser toolbars show or hide. - **Scales on small screens:** the circle is sized with `width: min(400px, 100vmin)`, so it shrinks to fit viewports narrower or shorter than 400px instead of being clipped. - **Screen reader support:** the SVG now has `role="img"` and a `<title>` of "Black circle", so it is announced rather than skipped. - **Minor CSS cleanup:** the reset now includes `box-sizing: border-box`, centring uses `grid` with `place-items: center`, and the SVG is `display: block`. ## What I left alone - **Page title:** `ae683f770` looks like a generated ID, and I had no meaningful name to replace it with. - **Colours:** I did not add dark mode support, since that would change the appearance. If you want it, add `color-scheme: light dark` on `:root` and `fill: CanvasText` on the circle.
