what changed from step 015

Nothing. The file is byte-identical to step 015.

What the model said

I didn't change `0.html`: I couldn't find anything in it that is wrong or missing in a way I could fix without guessing at your intent.

I checked these areas and they all hold up:

- **Document structure:** it has a doctype, `lang`, charset first, a title, and a `<main>` landmark with a single `<h1>`. The omitted `<head>`/`<body>` tags are valid HTML.
- **Mobile:** the viewport uses `viewport-fit=cover` with matching `env(safe-area-inset-*)` padding, and `text-size-adjust` prevents landscape font inflation.
- **Accessibility:** the fluid heading size has a `rem` component, so it still scales with user zoom, and the line height is unitless.
- **Theming:** `color-scheme` gives light and dark mode with no custom colours.
- **Robustness:** long words wrap, media is constrained to the column, and the empty `data:,` icon avoids a favicon 404.

The changes I could make all depend on what the page is for:

| Possible change | When it's worth it |
|---|---|
| A descriptive `<title>` and `<meta name="description">` | If the page is public or indexed; "0" tells a search engine or tab bar nothing, but I'd be inventing the text |
| Styles for links, lists, code blocks and tables | If the page will get real content |
| `box-sizing: border-box` reset | If you'll add layout beyond one column; it narrows the current text column from 40rem to 37rem unless adjusted |
| Explicit `<head>`/`<body>` tags | Only if you prefer it stylistically |

What is the page for, and what kind of improvement did you have in mind: content, visual design, or turning it into a fuller template?
