/* ============================================================
   OPEN WIDE, LaunchPoint flagship 02 (dentist)
   Design system per PRD section 1. Mobile first, 390px base.
   Clinical, restrained, editorial. No gradients, no shadows on
   buttons, no rounded pills, no cartoon anything.
   Easings are clinical ease-outs only, never springy.
   Palette rules (hard): --pulse never in buttons, nav, or
   badges. --gold never sets small text on light grounds.
