/* ============================================================
   BOOKING FLOW — patient-facing "agenda tu hora" (/agendar/{fid})
   Reuses design tokens + base elements from app.css (:root vars, fonts,
   .btn, .spinner, reduced-motion). This file owns everything specific to
   the day-picker / slot-picker experience — kept out of the admin-*.css
   trio because this is not dashboard chrome, it's the one screen a patient
   sees.
