> StyleX is a CSS-in-JS solution, not a CSS-in-React solution. Although StyleX been tailored to works best with React today, It's designed to be used with any JavaScript framework that allows authoring markup in Javacript. This includes frameworks that use JSX, template strings, etc.

I wouldn't be surprised if they avoided starting with "re" on purpose to avoid it seeming like this was a react only framework.
