   Builds on tokens.css. Accessibility overrides (WCAG 2.2 AA):
   - Cyan (#55c4e3) is 1.96:1 on paper, so it is never used for text or
     focus rings on light backgrounds. Eyebrows use navy-400 (6.66:1).
   - Focus ring is a solid 3px outline: navy-400 on light, powder on navy.
   - Form field borders use neutral-400 (3.34:1) to meet non-text contrast.
