I'm a massive CSS-in-JS skeptic but this is a very nicely thought out low-level tool for that stack. It's basically a JS version of SASS mixins (kinda). Most of my objections to CSS-in-JS are they are all poorly architected high-level abstractions taking a bad solution to a lower level problem. This feels like a good basis for a higher level tool that doesn't suck. And like I said - I say that as someone broadly skeptical of the whole topic.
