/* ============================================================================
   ScheduleInsight — Experience Design System  (assets/experience.css)
   Bold reinvention layer for the marketing site. Dark-first, light-aware.
   Co-exists with theme.js (which sets data-theme + the --mk-* brand tokens
   and supplies the light-theme overrides for the shared token names).
   ----------------------------------------------------------------------------
   Conventions:
     - Token names mirror the legacy set so theme.js light overrides keep working.
     - New primitives are additive; pages opt-in via classes / data-attributes.
     - Everything degrades gracefully without JS and respects reduced-motion.
