/* ==========================================================================
   Component: Select Dropdown System
   New trigger + content variants that compose with the locked Pattern 16
   (Hero Pill + Rich Description) to form the canonical Select Dropdown
   family. See /a/design-system/patterns/pattern-23-select-dropdown-system.

   Triggers (any of these can open any of the dropdown content variants):
     .hps-trigger          — Hero Pill (LOCKED, defined in hero-pill-select.css)
     .ee-picker__trigger   — Picker Pill (existing, defined in experience_editor/)
     .sd-trigger           — Traditional Select (NEW, defined here)

   Dropdown content:
     .hps-rich-drop        — Rich Description (LOCKED, defined in hero-pill-select.css)
     .sd-simple-drop       — Simple Description (NEW, defined here)
     .sd-search-drop       — Search-Tree (NEW, defined here)
   ========================================================================== */

   --compact modifier caps width at --field-max-width-compact at 640px+
   (mirrors .form-input--compact / .form-select--compact behavior).
