/* Ski Trail Divider — kabdalis2 design system. S-curved dashed ski tracks
   with a tiny skier gliding along the curve via CSS offset-path.

   Sizing approach (deliberate): CSS offset-path uses the raw px units of
   the path, so the skier and the SVG tracks must share one unscaled
   coordinate space. Everything is drawn on a fixed 600×80px "stage" that
   is absolutely centred in the root and uniformly scaled per size
   (sm ×.6 / md ×1 / lg ×1.35); the root only reserves the matching
   height. On screens narrower than 600px the root shrinks (max-width +
   overflow hidden) and the centred stage crops equally on both sides —
   no JS, no container queries. */
