Nothing. The file is byte-identical to step 020.
What the model said
I read through `0.html` and left it unchanged: it's already minimal, and I couldn't find an edit that would make it better rather than just different. I reviewed it by reading only, not by rendering it in a browser. What I checked: - **Layout:** the circle is centred with grid, and the `vh`/`dvh` and `vmin`/`dvmin` pairs are correct fallbacks for older browsers. - **Dark mode:** `color-scheme` plus `fill: currentColor` handles light and dark with no media queries, and the favicon adapts too. - **Accessibility:** `role="img"` with `aria-label` gives the SVG a proper name, and it sits inside `<main>` and `<h1>`, so the page has a landmark and a heading. - **Rendering:** `overflow: visible` stops the circle's antialiased edge being clipped at the viewBox boundary, so it's doing a job. - **Document head:** doctype, `lang`, charset, viewport, title and description are all present. The only nitpicks are judgement calls: - **Favicon support:** Safari's handling of SVG favicons is patchy, and a fallback would need a separate `.ico` or `.png` file, which breaks the single-file design. - **Favicon edge:** the favicon circle touches the edge of its viewBox, so `r='.9'` would give it breathing room at the cost of a smaller icon. If you have a specific direction in mind, such as animation, interactivity, a different size or colour, or a smaller file, tell me and I'll make that change.
