+   Collapsible is one independent disclosure: a trigger and its content, with no divider system. A plain trigger (no asChild) gets
+   a text-button look; with asChild the child (for example an HM Button) keeps its own style. Radix attributes drive the states.
+   No --hm-accordion-* token is referenced. */
