/* ============================================================================
   dmu-cardpicker — reusable search-dropdown picker with selected "cards"
   ----------------------------------------------------------------------------
   Extracted from templates/modules/meetings/form.php (the .dmu-mtg-rec-* block) so the
   widget can be reused across the app. Paired with:
     - js/modules/card-picker.js   (behaviour + auto-init)
     - templates/components/card-picker/card-picker.php  (markup helper)

   Structure rendered by the JS / PHP helper:
     .dmu-cardpicker
       .dmu-cardpicker-search
         > i.dmu-cardpicker-search-icon
         > input.dmu-cardpicker-search-input
         > .dmu-cardpicker-dropdown   (> .dmu-cardpicker-item / -group-header / -empty)
       .dmu-cardpicker-cards          (> .dmu-cardpicker-card)
       .dmu-cardpicker-hidden         (generated <input type="hidden">)

   Modifiers:
     .dmu-cardpicker--single                   single-pick variant
     .dmu-cardpicker[data-cards-layout="grid"]  selected cards in a 2-col grid
