What the model said

I made one change to `0.html`, because the file was already in good shape and there was little to fix without inventing content.

**The change:** I split the 170-character `padding` shorthand into four longhand declarations (`0.html:17-20`). Rendering is identical; it's just easier to read and edit. I kept the physical sides (`top`/`right`/…) rather than logical ones, since the safe-area insets are physical.

I haven't opened it in a browser, but the change is a purely mechanical expansion of the shorthand.

**What I left alone, on purpose:**
- **Document structure:** the omitted `<head>`/`<body>` tags are valid HTML, and `lang`, `charset`, and `viewport` are all present.
- **Dark mode:** the `color-scheme` meta already handles it with no extra CSS.
- **Typography:** the `clamp()` on the heading mixes `rem` and `vw`, so it still respects user zoom.
- **Favicon:** the empty `data:,` icon avoids a 404 request for `favicon.ico`.

**What would improve it, but depends on you:**
- **Title and description:** `<title>` and `<h1>` are both just "0". A meaningful title and a `<meta name="description">` would help, but I'd be guessing at what the page is about.
- **Styles for real content:** once there are paragraphs, links or images, it would be worth adding things like `text-wrap: pretty` and `img { max-inline-size: 100% }`. I didn't add rules for elements that don't exist yet.

If you had a specific direction in mind (visual design, real content, interactivity), tell me and I'll take it further.
