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 uses `width: 100vw`, which can overflow when a vertical scrollbar is present.
- **Better mobile centring:** the body now uses `min-height: 100dvh` (with `100vh` as a fallback), so the circle stays centred when mobile browser toolbars show or hide.
- **Scales on small screens:** the circle 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 meaningfully.
- **Reset cleanup:** the reset now includes `box-sizing: border-box` and covers pseudo-elements, and the SVG is `display: block` to avoid inline whitespace gaps.

## What I left alone

- **Page title:** it is still the hash `ae683f770`. It matches the SVG id, so it looked intentional, but a descriptive title would be better if this page is meant for people.
- **Colours:** the circle is still the default black fill on the default white background, with no dark-mode handling.
