/* =========================================================
   RAlly — Sphere DS reinterpreted for a GMP/cert SaaS
   ---------------------------------------------------------
   - Two-weight Pretendard hierarchy (Sphere's discipline)
   - Light canvas; navy ink (#0F2942)
   - Single accent: Coral #D97757, used sparingly for "current
     position / AI / urgent" — like Sphere's Active Red
   - Hairline borders, no glossy shadows
   - 4px sharp radius default; 999px pills; 8px on cards
   - Uppercase Latin micro labels with positive tracking
     (Sphere voice); Korean body in normal case
