What the model said

I made `0.html` more robust without changing how it looks on a normal desktop viewport: it's 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:** removed `width: 100vw` from `body`, which includes the scrollbar width and can cause overflow.
- **Better mobile centring:** `height: 100vh` became `min-height: 100dvh`, with `100vh` as a fallback, so the circle centres within the visible area when mobile browser toolbars are showing.
- **Circle scales on small screens:** the SVG is now `width: min(400px, 100vmin)` with `aspect-ratio: 1`, so it shrinks to fit viewports narrower or shorter than 400px instead of being clipped.
- **Accessibility:** added `role="img"` and `aria-label="Circle"` so screen readers announce the graphic.
- **Minor hygiene:** added `box-sizing: border-box` to the reset and `display: block` on the SVG.

## Left alone

I kept the title and the SVG `id` (`ae683f770`) as they were, since they look like generated identifiers something else may rely on. If the title is meant for people to read, it would be worth replacing with something descriptive.

"Improve" was open-ended, so I stuck to fixes rather than design changes such as colour, animation or dark mode support.
