/* ---------- Disclosure reveal ----------

   Both manifests sit OUTSIDE their <details> so they can span the full width
   instead of being trapped in one grid column / inline flex item, so the
   reveal is a :has() sibling toggle rather than native <details> flow.

   Default state in the base rules above is VISIBLE, so a browser without
   :has() degrades to showing all eight platforms rather than hiding five
   behind a control it cannot open.

   This block MUST stay BELOW the .manifest-line and .ep-manifest base rules.
   It has the same specificity as they do, so it only wins on source order -
   placing it above .ep-manifest silently let that later base rule re-show the
   episode manifest with all five tail platforms already expanded. */
