/* =============================================================================
   A4 - combobox, ported from HealthExpress by build/kit/port-css.py.

   Structure unchanged. Applied: 3 colour literal(s) -> on-accent, 9 rgb-channel
   tint(s) -> colour-mix, 0 hand-authored dark override(s) removed, 0 silent
   literal fallback(s) dropped, 0 black shadow(s) re-based on --ink,
   0 decorative glow(s) removed from bordered controls.

   No Bootstrap: these rules were already token-driven. Only the markup was ever
   coupled to it.
