/* ============================================================
   looptrace·explained — sage mist + ink + crimson tick.
   Same family as the looptrace app: crimson marks ONLY the
   currently-executing thing, so the eye follows execution.
   All animation is CSS-only; scenes get .is-playing from app.js
   (IntersectionObserver) and degrade to static, fully-legible
   final states without it or under prefers-reduced-motion.
