How do you integrate a CSS layers polyfill with PrimeVue?

[omnichronous]

CSS layers are very useful when working with PrimeVue, however if you're forced to support Safari 15 or other older browsers then you're out of luck.

I've managed to successfully integrate the PostCSS cascade layers polyfill into my project and it works great for Tailwind and the styles I write, however as PrimeVue builds and injects its styles in a very particular way, it sidesteps the polyfill entirely.

Is there any way to hook into the style injection process to apply such a polyfill? Thank you.
