What the model said

I made one change to `0.html`; the rest of the file held up to review and I left it alone.

## The change

At `0.html:72`, the `abbr[title]` rule now uses longhands instead of the multi-value shorthand:

```css
abbr[title] {
  text-decoration-line: underline;
  text-decoration-style: dotted;
}
```

Safari has long rejected the unprefixed `text-decoration: underline dotted` shorthand, dropping the whole declaration. Safari is also the one browser that doesn't underline `abbr[title]` by default, so the rule was failing exactly where it was needed. The longhands work everywhere. I didn't test this in Safari; it's from memory of the compatibility history, and I'm not certain which versions are affected.

## Left alone, but your call

`table { display: block }` gives you horizontal scrolling without a wrapper element, but some browsers have historically dropped table semantics for screen readers when `display` is changed. The fix is a scrolling wrapper `<div>` around each table, which costs you the classless approach. I kept the current behaviour since it's clearly deliberate.

## What I checked

- **Heading and section spacing:** the specificity of the rules resolves in the intended order, and margin collapsing gives the right gaps.
- **The `:last-child` margin reset:** it correctly leaves out `section`, `article`, `form` and similar, where zeroing the margin would break spacing with the next sibling.
- **Print styles, form controls, media sizing, safe-area padding and the `hidden` rule:** no problems found.

Anything else I could add (smooth scrolling, `scrollbar-gutter`, styling for `kbd` or `mark`, auto-sizing textareas) would be a matter of taste rather than a fix, so I didn't add it.
