`counter()` doesn't return a number, it ["represents"](https://drafts.csswg.org/css-lists/#counter-functions) a string. But even if `--c` is registered as a `<string>`: we do not (and can not) generally allow the result of `counter()` where `<string>` is allowed, because counters are understood layout time.

I don't think it's fine. But it's a separate issue, https://github.com/w3c/csswg-drafts/issues/12204.
