   Accessibility note on accent usage:
   - Ember Orange (#E87722) and Gold (#C9A84C) do NOT meet WCAG AA contrast
     as text on Cream/White, so they are used only decoratively (rules,
     underlines, the logotype) or as text on the dark Deep Umber background,
     where both pass AA.
   - Royal Purple (#6B3FA0) passes AA on Cream (≈6.4:1) and is the accent
     used where colored text must be readable.
   - textMuted (#9C9589) fails AA on Cream and is not used for body text;
     fine print uses textSecondary (#6B5E4E, ≈5.5:1).
