+// every avatar parent. A single-class override + `!important` would
+// be source-order dependent (both rules carry `!important`, so the

+// `.HeroAvatarExpanded.HeroAvatarExpanded` which doubles class
+// specificity and beats the single-class selector inside the
+// global `:has()`, so we win regardless of which CSS module the
+// bundler emits first.
