/* ==========================================================================
   AntJanus — Scroll-Driven redesign (demo 010)
   The page is a timeline: the scrollbar is a playhead, every section carries a
   keyframe ruler, and motion is bound to scroll position, never to a clock.
   All scroll-linked motion is progressive enhancement: it lives inside
   @supports (animation-timeline) + prefers-reduced-motion + [data-motion],
   and every base style is the finished, readable state.
