Work in progress: Make Hugo work with tailwindcss-jit

[bep]

Fixes #8343

[bep]

This is very much a work in progress. Some notes:

• This currently works on the basic level, and I have a test site where the build time goes from 3s to about 700ms, which is fine and dandy
• But because now the "rebuild trigger" now is mostly HTML templates, we got a challenge re. when to rebuild CSS
• That is solvable, but it would also bee cool to use the incremental build feature, which should be possible by having the PostCSS process being long-lived.

any news on this?

Maybe one way this could be solved if PostCSS would run after writeStats is completed, and we could reuse the hugo_stats.json to tell PostCSS that the change has occurred like I was trying in #8343 (comment) but in native way? I thought PostProcess would help, but it looks like writeStats runs after PostProcess
