  Tokens come from the brand guide (.claude/brand/BRAND_STYLE_GUIDE.md, v1.01).
  Contrast note: flat brand orange #FF7300 is only 2.9:1 on white. It is used for rules,
  fills and text on black. Large headings on white use --orange-strong (3.6:1, passes AA
  for large text); small orange text uses --orange-ink (5.6:1, passes AA).
