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 - **Small screens:** the circle now shrinks to fit when the viewport is narrower or shorter than 400px, instead of overflowing. - **No stray horizontal scrollbar:** removed `width: 100vw` from the body, which can overflow when a vertical scrollbar is present. - **Mobile height:** the body uses `100dvh` (with `100vh` as a fallback), so centring stays correct when mobile browser toolbars show or hide. - **Screen readers:** the SVG now has `role="img"` and a `<title>` of "Black circle", so it is announced rather than skipped. - **CSS cleanup:** added `box-sizing: border-box` to the reset, switched centring to `display: grid; place-items: center`, and set the SVG to `display: block`. ## Left alone - **Page title and id:** I kept `ae683f770` because I don't know what the page is for. A descriptive `<title>` would be better if you have one. - **Dark mode:** the circle stays black on white regardless of system theme. Following the theme would take `color-scheme: light dark` plus `fill: currentColor`, but it changes the look, so I did not add it.
