This is a test setup for an Issue I created on the Tailwind v4 repository. See: tailwindlabs/tailwindcss#16970
This setup actually proves that the issue is not with Tailwind, but probably somewhere in my own setup.
I've created two folders in src: application-project and components-project.
Both projects have Tailwind v4 CLI installed.
In the application-project I've intentionally removed all sources so that Tailwind doesn't pick up the example styles.
In the components-project I have a component-example.html where a single style is defined (text-center).
The application.html file in the application-project includes both the components.css and application.css files, in that order. My suspiscion was that the last file would reset the styles of the previous files. But that is actually not the case.
