/* ==========================================================================
   REVERON EMPIRE — Route System art direction
   Homepage compositions plus the pieces shared with the inner route pages
   (route hero, network, principles). Loaded on index, services, coverage,
   quote and contact; page-specific compositions live in pages.css.

   REVERON ROUTE SYSTEM: one route travels the whole page. It leaves the
   hero's vanishing point, runs down the editorial margin ("spine") of each
   section, branches into the content and ends at the destination marker.

   Colour bands (no hard cuts):
     black  — hero + introduction
     white  — service manifest + journey (journey turns dark at stage 03)
     black  — coast to coast + network
     white  — principles + process
     black  — destination + footer

   Mobile-first; desktop composition from 1024px. Scroll-driven states
   (.is-scrubbing, .is-interactive) are added by animations.js only.
