/* Smart Search dropdown -- Stage 3 Task 3 (static/js/smart_search/dropdown.js).
   Portaled to <body>, position:fixed -- Stage 1's fix for two real production
   bugs: an ancestor's overflow:hidden clipping the old dropdown, and a later
   sticky bar out-stacking it at the same z-index (see
   static/js/instant-search.js's positionDropdown()). This selector must stay
   a direct child of <body>: a position:fixed element re-anchors to any
   ancestor with its own transform/filter/backdrop-filter, which is exactly
   what the portal exists to avoid.

   Logical properties throughout so RTL (dir="rtl") mirrors row layout for
   free via inheritance from <html dir="rtl">; only the fixed box's own
   left/top/bottom/width are physical, and those are computed in JS because
   position:fixed placement has no logical equivalent.

   Visual language matches templates/catalog/partials/_home_search_panel.html
   (static/catalog/css/search_panel.css's .sugg block): white card, 16px
   radius, soft shadow, small-caps section labels, tinted icon tiles. */
