/* ---------------------------------------------------------------------
   Process section -- the roasting-process video (about.mp4 frames)
   following AboutSection's product intro. Structure mirrors coffee-hero.css's
   hero-sticky / hero-canvas pattern; unlike the hero, there's no reveal
   choreography beyond the loader -- the canvas just cuts in once ready.

   Sitting one z-index below AboutSection (see .about-scroll-section)
   matters only in the non-reduced-motion case, where process-section.js
   pulls this section up via its `handoffOverlapVh` config (negative
   margin, set inline since it must NOT apply to the reduced-motion static
   layout) so this section's own sticky pin is already engaged -- fully
   pinned and visible underneath -- before AboutSection starts fading out.
   That overlap is what makes AboutSection's fade-out (about-section.js's
   `_updateHandoff`) read as a crossfade into this section instead of a
   hard cut.
