/* (a) Primary-button surface. §13.2 specifies #d96f00 with white label, which
       measures 3.37:1 — below the 4.5:1 WCAG 2.1 AA threshold for 14px text.
       The button surface therefore uses the spec's own darker orange
       (#b45a00, 4.77:1) and brightens to #d96f00 on hover. Brand orange is
       unchanged everywhere it is not carrying small white text (active-nav
       rule, section accents, serif figures — all ≥3:1 as large text or
       non-text). To follow §13.2 literally, set --orange-cta: #d96f00.

   (b) §13.4 names a purple chip for Advisory board while §13.1 prohibits
       purple anywhere. §13.1 wins (it is the CI-gated rule); the chip uses a
       warm sand tint that stays distinct from the teal/blue/gray siblings.

   (c) §13.2 specifies 1px #b9b4a7 field borders, which measure 2.02:1 against
       paper — below the 3:1 WCAG 1.4.11 threshold for control boundaries.
       #8f8a7c (3.36:1) is the nearest tone that passes. Revert by setting
       --field-border: #b9b4a7. */
