/* =========================================================================
   projects-motion.css  —  Motion-graphic enhancements for the Projects area.

   1) FLAGSHIP REEL — a pinned, horizontally-scrubbed showcase of the top
      projects. Progressive enhancement:
        • default (mobile / no-JS / reduced-motion)  -> panels STACK vertically
          (safe, no overflow, fully readable)
        • desktop + motion-ok (JS adds .is-horizontal) -> horizontal pinned reel
   2) CUSTOM CURSOR — a follower ring that morphs to a "View / Watch / Code"
      pill over [data-cursor] media. Desktop + fine-pointer only.
   3) MAGNETIC BUTTONS — handled in JS; this file only hides nothing.

   Everything recolors via the live accent vars (blue/red/orange/mono).
