Which tailwind version?

I am seeing this with 4.1.18

I was able to reproduce this on Tailwind CSS v4 using the new-york style.
The docs reference AlertAction, but the new-york v4 registry template
(apps/v4/registry/new-york-v4/ui/alert.tsx) does not define or export it.

I can take this and submit a PR adding AlertAction to the new-york v4 alert template to align the generated output with the docs/examples.
