/* ==========================================================================
   AGENT IVAN — design system

   Concept: an operations dossier. "Agent" reads as logistics precision and
   accountability — a mission board, a manifest, a tracked route — never
   spy-thriller costume. The cold layer (mono data, grid, globe, numbered
   section tags) frames the LOGISTICS. The warm layer (real faces, children's
   letters, sand paper) carries the PEOPLE. That contrast is the design.

   Colour rule that matters: nothing sets colour by descendant context.
   Surfaces declare their own foreground via --fg tokens, so a light card can
   never inherit white text from a dark section. (That bug shipped once.)
