/* =============================================================
   DEXTROLOGY — Upper GI Endoscopy Course (Arabic-first, RTL)
   Design system + page styles
   -------------------------------------------------------------
   Brand: deep navy + metallic silver (from the Dextrology logo).
   Accent: one locked teal, used sparingly for emphasis/success.
   Radius rule: buttons = pill, cards = 14px, inputs = 10px.
   Direction: authored mobile-first with logical properties so the
   layout works in RTL (page language) and LTR embeds alike.
   Type: Cairo carries both Arabic and Latin. Arabic script gets
   no negative letter-spacing and taller line-heights; tracking
   is reserved for Latin-only elements (wordmark, tagline).
