   uses dark-context CTAs intentionally on most pages, so re-assert the button

   sits at 3.06:1, eyebrow-on-paper at 2.83:1 — both below WCAG AA 4.5:1.
   These derived tokens darken Signal just enough to pass AA at small
   sizes on light/orange backgrounds, while staying inside the orange
   brand family. The base --signal token is unchanged and still drives
   accents, dots, rules, large headings, and hover states.
