How can I add prefix to Tailwind CSS v4?

[manuelhpineda]

I have my entire project running with a prefix of
module.exports = { prefix: "tw-", }

How can I add this to the new tailwind css v4 config? I also tried using @config "../../tailwind.config.js" but it give me "the prefix is invalid" if I remove the "-" it doesn't work at all.
