/* =====================================================================
   Premier Pickers — custom date + time pickers
   ---------------------------------------------------------------------
   Drop-in enhancement for <input type="date"> and <input type="time">.
   Hides the native input, renders a styled trigger button next to it,
   and opens a modal with a calendar grid (date) or wheel columns (time).
   Theme: navy + gold + cream — matches booking-portal + admin styles.
   No JS framework dependency. See premier-pickers.js for behavior.
