/* ==========================================================================
   SGFX Gold Rush — Expo 2026

   The entry is a bullion warrant. SGFX navy is the ink it is printed in, not a
   dark-mode chrome: the flow sits on a sheet of cool bond paper on a drenched
   navy field, because a visitor reads this on their own phone under the lights
   of a bright exhibition hall, where paper beats a dark UI.

   Three colours, three jobs, and they never swap:
     navy  = the ink       (rules, type, structure)
     cyan  = the system    (focus, the live step, the primary action)
     gold  = the prize     (the coin, the serial, the struck seal)

   Corners are square. Security printing has no rounded corners; only the
   things a thumb lands on get 2px of softening.
