/* ============================================================================
   Form kit — shared chrome for admin forms
   ----------------------------------------------------------------------------
   Section headers, collapsible boxes, toggle switches, validation states, the
   upload dropzone and the sticky save bar. First built for the product form;
   lifted here so every form on the platform looks the same instead of each
   page re-inventing (and drifting from) the same handful of components.

   Sizing/typography deliberately lives in ui-density.css, which loads after
   this file. Anything here that sets a font-size is a deliberate exception.
