Tailwind CSS v4 styles not applying on page refresh with PrimeNG 21 (Angular 21 + Nx)

[viniciuscigma]

I am facing an issue where Tailwind CSS v4 utility classes are not being correctly applied to PrimeNG components and standard HTML elements in a workspace using Angular 21, PrimeNG 21, and Nx.

Upon initial page load or a manual refresh (F5), Tailwind utility classes do not take effect. The components revert to their default PrimeNG styles, and Tailwind-specific utilities (including Dark Mode) are completely missing. This occurs despite the styles being correctly imported in the main stylesheet.
