/* ==========================================================================
   MetaBot Solutions — V5 design system
   Concept: THE ORG CHART, MADE LIVING.
   An editorial, annual-report aesthetic: near-black ink, deep signal green,
   one warm ivory, oversized grotesk display type, chapter-numbered sections,
   and a living node-map as the brand's signature diagram language.
   Dark ink = the machine workforce. Ivory = the human chapter. Green = work
   in motion. Amber reserved strictly for the human checkpoint.
