Serving CSS file through Head does not work.

Hello, I'm building a toy project with caldera to make sure it could be useful in a future project.
First of all, I have to say that all JS / TS related features work great out of the box and the api design is very simple, which is good for something so powerful.
But, my problem arise when you try to serve css from the same server.

Here is an example repository that can be used to reproduce the whole affair.
As you can see I'm using tailwind, but that should be unimportant in that matter as they generate a static css file at compile time.
The problem is located on the page load, Head does its job of writing to the head tag, but the call to retrieve that css is always answered with an index.html that, I assume, caldera did generate.

What I think is happening is that you catch all incoming request and always serve the caldera root, but that cannot work to support other ressources.
Maybe I'm missing something, I would be glad to know that caldera just work, but for the moment it seams to only support external css, as the examples shows.

This line seams to be the culprint, I'll try doing a PR.
