What the model said
I made one change to `0.html`, and it is untested: the stylesheet was already in good shape, and the rest of what I found were judgement calls I left alone.
## What I changed
`font: inherit` on the form controls was also wiping out the bold weight browsers give `<optgroup>` labels, so group labels looked like ordinary options. I added a rule restoring it at `0.html:132`:
```css
optgroup {
font-weight: bold;
}
```
## What I couldn't do
I wanted to render the stylesheet against a test page in a browser, but the shell command to look for one was denied in this session. Everything here comes from reading the CSS, not from seeing it rendered.
## What I noticed but left alone
- **Placeholder content:** the title and `<h1>` are both "0" and there's no `<meta name="description">`. I didn't invent content for a page whose purpose I don't know.
- **Bare media between paragraphs:** an `<img>` or `<video>` placed directly between paragraphs, not inside a `<p>` or `<figure>`, gets no space below it. Fixing it means making media block-level, which would change how inline images behave.
- **`table { display: block }`:** this gives horizontal scrolling without a wrapper element, but it has historically cost table semantics in some screen readers. The alternative is a wrapper `<div>`, which breaks the classless approach.
- **Nested sections:** a section that is the first child of a non-first section (e.g. `<article><section><h2>`) misses the 2rem top spacing. It's a rare structure, and the fix would make the heading selectors more complicated.
If you tell me what the page is for, I can fill in the title, description and content.
