/* ═══════════════════════════════════════════════════════════════════════════
   stepwind.app — StepWind's own identity: time, wind, and reversal.
   Atmosphere = drifting wind streaks + breathing glows + the timeline dot-grid.
   The design system borrows the APP's operation colors (create/modify/move/
   rename/delete) as accent rails. Motion is transform/opacity only — no blur,
   no backdrop-filter — and everything respects prefers-reduced-motion.
