Re: [csswg-drafts] [css-contain-3] Move style() to the feature level in the grammar (#7073)

To clarify the difference here, the two options look like…

A **feature-level** syntax might be a bit simpler from the spec/implementation side:

```css
@container card-component (style(--card: feature) and style(--mode: dark)) or style(background: maroon) { … }
```

But the current **higher-level** syntax provides a bit more sugar for authors, since the function is only required once, and can contain multiple `style()` conditions:

```css
@container card-component style(((--card: feature) and (--mode: dark)) or (background: maroon)) { … }
```

My thoughts:

- My preference is for the higher-level syntax sugar, but it's not a big difference, and there's no functionality at stake
- This decision would likely apply to any new non-size features added in the future (eg 'state queries')
