/* ==========================================================================
   QuietQuality — scenes-hub.css
   Scene styling shared by the 5 hub / content pages
   (services, case-study, staff, method, column).
   Loads immediately after motion.css and reuses its scene classes
   (qq-htrack-*, method-runner/-sticky/-connector, qq-case-grid,
   qq-video-overlay). This file adds only the page-specific pieces that the
   flagship index.html did not need. Brand tokens come from site.css :root.
   Every effect degrades to a static, legible state under
   prefers-reduced-motion.
