/* ==========================================================================
   The Boardroom Edit, version five motion pass.
   1. Home hero: slow push-in on the sunset sky and skyline, a warm overlay
      that drifts from cream to dusk, and a staggered fade-up of the hero text.
   2. Background-video bands on inner pages (same treatment as the home band).
   Only transform/scale/translate and opacity are animated. Everything that
   moves sits inside prefers-reduced-motion:no-preference.
