what changed from step 049

Nothing. The file is byte-identical to step 049.

What the model said

I reviewed `0.html` and made no changes: I couldn't find a defect or an improvement that isn't just a matter of taste.

This was a read-through only. I couldn't test it in a browser, because the command to look for an installed one was blocked in this session.

## What I checked

- **Document head:** it has the doctype, `lang`, charset, viewport with safe-area handling, `color-scheme` and an empty favicon to avoid the 404. The omitted `<head>` and `<body>` tags are valid HTML.
- **Heading and section spacing:** I traced the specificity of the heading, `hgroup` and sectioning rules, and each override wins where it should.
- **Trailing margins:** the `:last-child` reset correctly beats `details[open] > summary` and `body > header` when those are the last child.
- **Overflow:** long words, `pre`, tables, media and form controls are all constrained. `break-word` is the right choice over `anywhere`, which would collapse table columns.
- **Internationalisation:** logical properties are used throughout, so right-to-left text works. The one physical property is `overflow-x`, and its logical equivalent isn't widely enough supported to swap in yet.
- **Forms:** font inheritance keeps inputs at 16px, which avoids the iOS zoom on focus.
- **Print:** the table display is restored, URLs and abbreviations are expanded, `details` content is revealed and the break rules are sensible.

## What would actually improve it

Both of these need input from you:

1. **Content:** the page is only `<title>0</title>` and `<h1>0</h1>`. With real content, a `<meta name="description">` and a meaningful title would be worth adding.
2. **Line length:** `40rem` in `system-ui` is roughly 85–90 characters per line, above the usual 45–75 guideline. If this is for long-form reading, `36rem` or so would be more comfortable; I left it, since it's a design choice.

If you had a particular direction in mind, such as visual design, a colour theme or a smaller stylesheet, tell me and I'll make the change.
