Re: [csswg-drafts] [css-values] Add `valid-empty`-like value (for CSS Custom Properties) (#10441)

@LeaVerou I’ve been thinking about other syntaxes as well. We probably have to define if there are use-cases outside of custom props for this keyword.

Some high-level ideas (not happy with them) working around CSS’s case-insensitivity (I still like the explicit nature of `valid-empty`):
```css
.meow {
  --foo: ();
  --baz: !valid;
  --bar: *;
}
```
