[V4] - How to get v4 going with Deno and a separate CSS entrypoint?

[bebraw]

I set up a small demonstration at https://github.com/bebraw/tailwind4-demo . The problem is that the setup doesn't find tailwindcss for some reason when running through Deno.

It would be great if you could point me to a working example where an external CSS file is used as an entry point for loading Tailwind or help me amend this example to a working state.
