   Dark navy is the canonical treatment; light alabaster is the alternate.

   Gold (#D4A355) measures 2.05:1 on Alabaster, well under WCAG AA, so it is
   NEVER text in light mode. It appears there only as a graphic: rules, the
   mark's accent chevron, borders. On Navy it measures 7.2:1 and is safe as
   text, so --accent-ink resolves per-mode rather than being a fixed gold.
