What the model said

I made one small change to `0.html`, because the file is already in good shape and there was little to fix without guessing at your intent.

**The change:** at `0.html:15`, `margin: 0 auto` became `margin-block: 0; margin-inline: auto`. This matches the logical properties used elsewhere in the stylesheet (`max-inline-size`, `margin-block`), so the centring works in any writing mode. I haven't opened it in a browser, but the rendering should be identical in the current horizontal layout.

**What I left alone:**
- **Document head:** the doctype, `lang`, charset, viewport, `color-scheme` and the empty favicon are all already there.
- **Layout and type:** the safe-area padding, fluid heading size and `text-wrap: balance` needed no fixes.
- **Omitted `<head>`/`<body>` tags:** this is valid HTML and looks like a deliberate style choice.

**Would need your input:**
- **Title and description:** the page's title and heading are both just "0". A more descriptive `<title>` and a `<meta name="description">` would help, but I'd have to invent the wording.
- **Styles for future content:** the page has no paragraphs, links or images yet. If those are coming, I can add defaults for them (responsive images, `text-wrap: pretty`, link and focus styles).
