/* ──────────────────────────────────────────────────────────────
   Combo Control — Custom Select Dropdown
   ──────────────────────────────────────────────────────────────
   Ersetzt native <select>-Elemente durch gestylte Dropdowns,
   konsistent mit dem Zummit Design-System.

   Nutzung:
     <select class="z-combo ...">          → auto-init via zComboInit()
     zCombo(selectEl)                      → manuell upgraden
     selectEl._zCombo.refresh()            → nach Options-Änderung

   Abhängigkeiten:  combo.js, Design-Tokens aus _layout.html
