   PACT — Design System
   Palette: Obsidian (ground), Silver, Gold, Ruby, Emerald
   Rule: light backgrounds always carry dark ink; dark
   backgrounds always carry light silver/paper text. Gold,
   ruby and emerald are used only as accents, never as body
   copy on a background that would break contrast.
