   Design system: "calibration certificate / torque card".
   Light = calibration-cert paper. Dark = tool steel.
   Display Archivo 800 · body Public Sans · values IBM Plex Mono.
   Accents: torque orange (--accent) + verify green (--verify).
   Signature: the provenance spec-chip + the diagonal witness mark.

   Contrast floor 4.5:1 in BOTH themes (hexes verified arithmetically; worst
   text pair light 4.69, dark 5.28). Radius <= 4px. No pill buttons, no glow
   shadows, no pure #000. prefers-reduced-motion / forced-colors / prefers-
   contrast all honored below.

   Tokens are defined THREE times: :root (light), the media-dark block, and the
   explicit [data-theme=dark] override — the suite dual-theme contract.
