/* Canadian FAIT Research — shared cinematic scene system.
   Generic primitives (.scene / .scene-scrub / .scene-sticky / .scene-content / .is-in)
   are wired by /scenes.js on every page. Overlay-only chrome (#cinematic-intro,
   ci-close/ci-progress/ci-dot, html.ci-lock) is homepage-specific and stays here
   too since it's small. Homepage bespoke illustrations use an "hp-" prefix since
   they're one-off visuals, not shared vocabulary. Per-batch bespoke scene CSS for
   other pages gets appended below in its own labelled section, reusing the same
   .scene-* primitives. */
