/* Smooth open/close via grid-template-rows trick (Chrome 117+, Safari
   17.4+, Firefox 124+). The grid track collapses from 1fr (auto height)
   to 0fr without an over-shot height ceiling, so close is as snappy as
   open and there's no animation lag when content is short.
   `overflow: hidden` on the panel clips inner padding cleanly when the
   track size is 0; `min-height: 0` on the child overrides the default
   `min-height: auto` that would otherwise prevent collapse below the
   content's intrinsic size. Older browsers snap without animation. */
