Extending @tailwindcss/typography to Custom Elements in Tailwind 4

[raffazizzi]

I'm trying to extend the @tailwindcss/typography plugin so that the styles applied to .prose p also apply to a custom element.

I tried

@layer components {
  .prose custom-p {
    @apply prose-p;
  }
}

but in Tailwind 4, this results in an error: Cannot apply unknown utility class: prose-p

Since prose-p is not a standalone utility, I now need to manually replicate the styles.

Is there an official or recommended way to find and reuse typography styles in Tailwind 4 without manually copying them? Thanks.
