   Laurenceo · shared design system
   Used unchanged by laurenceo.com and intelligence.laurenceo.com.
   Brand #213547 on a flat #0F0F0F base. Inter throughout (variable, optical sizing).
   Accent system (each colour means one thing, everywhere):
     lavender  AI Governance and Regulation
     rose      Cybersecurity and AI Safety
     sky       Data Protection and Privacy
     mint      Infrastructure and Connectivity
     gold      Insurance, AI and Markets
   #213547 is used only as a fill: primary buttons, feature panels, the
   current-page state of the primary pill, and text selection.
