Passthrough fork maintenance

[Sytten]

Hi!

I posted on here cagataycivici/primevue-tailwindcss-presets#2 but not getting a response. I believe there is enough people invested in keeping the passthrough method alive. The @apply method is problematic for many reason, especially if you have multiple codebases that can I inject styling in a given page.

Now, I made some suggestions on how to make better it for contributors to maintain those themes. If someone from primefaces can act on them I would really appreciate.

Thanks
