   Project Lunar — Scrollytelling Stage (v2)
   Full-viewport mascot background per scene, content
   overlays via z-index. Scroll-driven transforms on the
   mascot image deliver the "alive on scroll" feel.

   Upgrade path: swap .scene__stage-img (<img>) for
   <canvas data-frame-canvas> + frame sequences when
   Higgsfield DoP pipeline is re-enabled.
