/* ===========================================================
   Ava Sani Booking — mobile-only customer booking site.
   A separate design system from the staff admin and the partner
   portal: warm off-white canvas, one coral accent, big rounded cards,
   dark hero landing — built to read as a real consumer app, matching
   the client's reference screenshot's visual language (mirrored for
   RTL: icons/text stay put, but flex/flow direction follows RTL).
