What the model said

`0.html` was already in good shape, so I only made two small CSS changes. I haven't opened it in a browser.

## What I changed

- **Trailing margin:** the last element in `<main>` no longer adds its 1rem bottom margin on top of the body padding, so the spacing at the bottom of the page matches the top.
- **Embedded media:** `canvas` and `iframe` are now also capped at the container width, so they can't cause horizontal scrolling on narrow screens. `iframe` is left out of the `block-size: auto` rule, because that would collapse it to the default 150px height.

## What I left alone

- **Missing `<head>` and `<body>` tags:** these are optional in HTML and the omission looks deliberate.
- **Viewport, safe-area padding, colour scheme, fluid heading size and text wrapping:** all fine as they are.

## What depends on your content

- **Title and heading:** both are the placeholder `0`. A descriptive `<title>` is the biggest remaining gain for accessibility and search.
- **Meta description:** there isn't one. I didn't add one because I'd be inventing the text.
