/* ============================================================
   MODAL-DIALOG COMPONENT (cohorts.php and similar admin pages)

   Namespaced as .modal-overlay / .modal-dialog rather than reusing
   the bare ".modal" class above. This file already has a DIFFERENT
   legacy modal system further up (.modal / .modal-content / .show)
   where ".modal" itself IS the full-screen overlay. Reusing ".modal"
   here for the inner dialog card collided with that rule: because
   both rules have equal specificity, the later one in the file wins
   property-by-property rather than wholesale, so the "dialog" ended
   up inheriting position:fixed/width:100%/height:100% from the
   legacy rule while also getting display:flex from this block —
   producing a full-viewport white box instead of a centered card.
   That's the "modal won't open" bug: the overlay's own show/hide
   toggle (.modal-overlay.open) was working fine the whole time; the
   inner element just weren't a modal box.
