Implementation checklist
  • Use token variables only. Keep accent usage sparse and intentional.
  • Keep panel edges square with no shadows; hierarchy comes from rules and typography.
  • Reserve serif for key display headlines only. Operational UI remains sans/mono.
  • Maintain contrast on all controls and preserve visible focus ring on keyboard navigation.
  • Keep motion subtle: hover/focus feedback and short numeric count-up only.
