/* ══════════════════════════════════════════════════
   CLIENTS — Section 7
   Split layout (text left, vertical marquee right),
   mirroring What We Do / Services. The marquee is the
   same infinite-scroll concept as before, rotated 90°:
   3 columns instead of 3 rows, translateY instead of
   translateX, top/bottom edge fade instead of left/right.
   No JS — pure CSS animation.
   Depends on: tokens.css, hero.css (bgs keyframe)
