What the model said
I made some improvements to `0.html`, keeping the look the same: 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 used `width: 100vw`, which overflows when a vertical scrollbar is present. It's now sized with `min-height` only. - **Correct height on mobile:** `100dvh` is used, with `100vh` as a fallback, so the circle stays centred when the browser toolbars show or hide. - **Scales on small screens:** the SVG was fixed at 400×400 and got clipped on narrow viewports. It now shrinks to fit and stays square, capped at 400px. - **Accessible to screen readers:** the SVG now has `role="img"` and a `<title>` of "Black circle". Hovering over it will show that text as a tooltip. - **Minor CSS tidy-up:** the reset now includes `box-sizing: border-box`, centring uses `grid` with `place-items`, and the SVG is `display: block`. ## What I left alone The page title and the `id` are still `ae683f770`, since they look like generated identifiers that something else may depend on. A descriptive `<title>` would be better if nothing does. The circle is still hard-coded black on the default white background, with no dark-mode handling.
