📝 parser error with forward slash in tailwind directive

[mpeg]

Environment information

A forward slash within a @utility tailwind directive name throws an error when parsing it, as in the repro

Prettier is able to parse this kind of css, while biome throws an expected `{` but instead found `/` error

While the css is not valid, tailwind automatically escapes it, incidentally there is also an issue where tailwind doesn't allow the pre-escaped utility name which would work with biome. Still, maybe this is worth a fix on both sides

Would you mind also posting a tailwind playground? It's unclear if this is actually valid syntax.

Sure thing, here you go: https://play.tailwindcss.com/ik6aLCMczb

It is technically not valid syntax in css, but it is in tailwind as it escapes the forward slash automatically
