 * The starting values were sampled from Covercy ONE on 2026-09-21. Two of
 * them do not meet AA as text and are kept for what they can carry:
 *   #768894 (muted labels) is 3.67:1 on white — it is the input border
 *           (3:1 is what a control's edge needs); muted TEXT is #5c7080.
 *   #00be82 (success) is 2.42:1 on white — decoration only (the stripe on
 *           a success notice); success TEXT is #006b49 on its tint.
