Releases

@primer/css@22.3.0

Minor Changes

• #30805cb880b Thanks @jonrohan! - Adding a classnames export that has a list of all unique CSS classes in the library

Patch Changes

• #3079d735d75 Thanks @copilot-swe-agent! - Replace the universal * subject in the .pagination responsive rules with tag-bucketed selectors (> a, > span, > em). A universal subject compound (.pagination > *) forces Blink to test the rule against every direct child on every style recalc; bucketing by the actual child tags lets the engine fast-reject it, reducing wasted selector-matching time without changing the rendered output.
