Using it

Do

  • Keep cyan reserved for the one probe, focus rings, and exceptions.
  • Tune neutrals cool to the ink-navy ground; let depth and ink ramps carry the survey.
  • Use the depth scale as a documented certainty ramp, not decoration.

Avoid

  • Do not spread cyan as a panel fill or background wash.
  • Do not lighten the ground toward bone or white.
  • Do not let semantic success/warning/error become visually primary.
