"beyond a junior level" -- I doubt this will change your mind, but this post is from the author of Tachyons, a "pre-Tailwinds" competitor that didn't get the same traction:

https://mrmrs.cc/writing/scalable-css/

And the tldr is that he downloaded and read the CSS for several major websites at the time (post is from 2016) and they were all hodge-podge of terribleness.

Maybe all the devs writing that CSS were junior, but imo it's more than CSS just doesn't have the abstractions to match the level of OCD/bespokeness that designers spec into every Figma -- move this box by _this_ much / _that_ much / etc.
