This is a really cool concept.

I'm not a fan of Tailwind's approach if I'm being honest, and while at first glance they look similar, from a practical standpoint Turbo is something I can actually see myself using to create landing pages and design systems without having to conform to Tailwind's insane naming scheme. The conditional styling also looks very intuitive.

To that end I appreciate the Turbo vs Tailwind page, and I'll definitely take this for a spin at some point (not having to explicitly exclude Sass or remove unused styles seems like a refreshing way to handle performance).

The in-browser compiler is also something I've never seen before, and from what I'm understanding that makes it extremely portable; no package manager necessary.
