Styling Linear for the future with StyleX

Kenneth Skovhus: The client went from injecting hundreds of CSS rules during a navigation to zero. Arguably the more valuable change, though, is that styling now has much clearer boundaries at Linear. Components have explicit styling contracts, precedence is deterministic, and many patterns that used to depend on convention or the cascade are now enforced by tooling. I wrote about StyleX last year and maintained a very similar atomic CSS system at Yahoo. Linear just finished a 1,000-PR migration onto it, in part to help agents write UI at scale. Source
