/* ============================================================
   Smart21Brain — Games hub hero
   Two-column hero: copy on the left, an alpha-keyed video of the
   Smart21Brain mascot on the right. The hero's own backdrop is a
   full-bleed looping video (.hero-bg-video) instead of the flat
   brand gradient other .hero-plain sections use — just a thin dark
   wash on top (below) so the white copy stays readable over it.
   Mouse movement gently "spins" the mascot by scrubbing the clip;
   a rAF easing loop keeps that scrub smooth instead of jumping
   between frames.
