/* Drive SI landing v2 (DELTA-001388 designer, 2026-10-18).
   Look: The Federation Chronicle and the Camelot Chrome Utopia canon (chronicle/design-package/SITE-LOOK.md).
   Unbounded + Instrument Sans, self-hosted. White pages, pictures lead, 6px radius, no shadows.
   One story in ten scenes; each scene has its own layout. Motion: one rise on load, scroll reveals,
   pinned scenes, a horizontal sequence and gentle parallax. All of it stops under prefers-reduced-motion. */
