Syntax highlighting breaks with new Tailwind v4 custom directives

[YvetteNikolov]

Hello!

Love using your extension, especially with Tailwind. In my case, I often need to write Tailwind classes in CSS.

After upgrading to Tailwind V4 I noticed that two custom directives break the syntax highlighting:

@variant
@utilities

Could you look into fixing this?

Thanks for the great work.
