   Colombo Marathon 2026 — "Lace Up For a Cause"
   Main Stylesheet (v7)

   Design principle: ONE dominant brand color (blue) drives all
   interactive elements. Red/green/gold are reserved for meaning
   (error / success / highlight) rather than decoration, except
   for the event-distance cards where 4 distinct colors genuinely
   help tell the options apart at a glance.
