Thanks for the comment. It reminds me that examples should be more real-like. Hehe. Because, yeah, I would absolutely use a custom property for it. Same with .card, a simple example which in practice may be more precise, yes.

Global scope is for base rules, yes. Rhythm, typography, maybe colors only. Still it's great to be able to style these design layers globally!

I'll adjust the examples to reflect this. Thanks for the lesson!

PS: hard to debug bugs? The inspector shows styles handily for global styles!
