How to render css from Tailwind 4 in ssr?

[sebastianwd]

Running a fresh create-tsrouter-app with the Tailwind add-on.

Steps:

1. Build the application and serve it with pnpm start,
2. Check the network tab
3. Tailwind styles are not rendered server side

I've never had a problem making the server html come styled when using Next.js and Tailwind 3. This might seem minor but in slow connections and with no cache I can easily get a flash of unstyled content.
