   PROPOSED: "Datum Grammar" — promote the orange reference-line vocabulary
   (already living in .storybook/docs.css) INTO the component layer, and extend
   it with two engineered primitives the system doesn't have yet:
     · .ct-datum-scale  — a measured reference line (ruler) with a marked origin
     · .ct-card--datum  — a corner registration mark, like an engineering drawing
   a11y rule kept intact: orange-as-TEXT = accent-active (orange.700);
                          orange-as-EDGE/RULE = accent (orange.500).
