/* CORD brand. Zinc neutrals and the cool sweep: the four parts, in CORD order, are neighbouring hues on one
   teal → violet gradient (cluster teal, optimize blue, research indigo, detection violet). Research (this repo's
   reports) drives --accent.
   Token contract (every brand defines the same names): see render/brand/README.md.
   --part-*: each CORD part's accent, text-safe on --surface in the current theme (4.5:1 or more).
   --part-*-mark: the mid-tone used in logos, 3:1 or more on both white and near-black, so one SVG works on both.
   --brand-rule: the sweep itself, for the report's hero rule and header line (cord only; other brands omit it). */
