Generated page is missing CSS

Everything works well for me except that the generated pages never have a css.
The generated CSS is always:

@tailwind base;
@tailwind components;
@tailwind utilities;

The generated pages are missing all the style.

Anyone else encounters this?

Start by reproducing the generated page and inspect the path that generates or processes its CSS, since no source file or test is named. Confirm that the generated CSS contains compiled styles rather than only the Tailwind directives, and verify that the rendered page is styled.
