   dark.css — Dark Sections: Trust Strip · AIR · Stats · CTA · Footer
   axsysTek V4 "Controlled Velocity"

   SELECTOR NOTE (Phase 1 temporary):
   Trust Strip, AIR, Stats, CTA use Drupal paragraph section IDs.
   Footer uses plain `footer` tag + `.region-footer` child.
   Phase 2: Replace all with .section-* classes once
   page--front.html.twig adds semantic class names.
