What the model said

I made a few robustness and accessibility fixes to `0.html` while keeping the design the same: a black 400px circle centred on the page. I haven't opened it in a browser to check.

## What changed

| Change | Why |
|---|---|
| Removed `width: 100vw` from `body` | `100vw` includes the scrollbar width, which can cause a horizontal scrollbar. |
| `height: 100vh` → `min-height: 100vh` with a `100dvh` override | Centring stays correct on mobile browsers where the URL bar changes the viewport height. |
| SVG size `400px` → `min(400px, 100vmin)` with `aspect-ratio: 1` | The circle is still 400px on normal screens but shrinks instead of being clipped on smaller viewports. |
| Added `role="img"` and `aria-label="Black circle"` to the SVG | Screen readers now announce the graphic. |
| Added `box-sizing: border-box` to the reset | Sizing stays predictable if padding or borders are added later. |

## What I left alone

- **Title and `id`:** both are still `ae683f770`, since it looks like an identifier something else may depend on. A human-readable `<title>` would be better if nothing does.
- **Visual design:** "improve" was open-ended, so I didn't add colour, animation or a dark-mode style.
