/* ============================================================
   TENDI DATE / TIME PICKER -- flatpickr, re-skinned onto tendi-tokens.css
   ------------------------------------------------------------
   Replaces the jQuery-UI datepicker, which carried a dark legacy theme from
   style.css and could only be dragged part-way onto the design system.

   Nothing here hardcodes a colour: every value is a var(--token), so the picker
   re-themes with the rest of the app. Loaded AFTER flatpickr.min.css so these
   rules win without !important soup.

   House rules honoured:
     - a floating overlay, so --shadow-overlay IS allowed here (flat surfaces are not)
     - no glyph icons: flatpickr's prev/next arrows are already inline SVG
     - no translateY hover: days respond with fill + border, never movement
     - month picker runs in `static` mode, so there is no bare native <select>
