/* zsybcom combobox — progressive enhancement around a native <select>.
   The original <select> is kept in DOM (visually hidden) so form submission
   and screen readers still work; the visible UI is a button trigger and a
   floating popover with search + keyboard-navigable list.

   Sizing matches the task-bar slot reserved by topbar.css
   (180px wide, 30px tall) so there is no layout shift on enhancement. */

   of the unstyled native picker between DOM parse and enhancement). */
