/* LGMA Eligibility Checker — Pre-screener form
   Humana Design system tokens, light/dark via prefers-color-scheme.

   Two tokens are derived from the brand palette specifically to pass
   WCAG 2.2 AA contrast at the small text sizes they're used at:
     --muted-text  (darkened --muted,   4.5:1 on --card in light mode)
     --accent2-ink (darkened --accent2, 4.5:1 on --card in light mode)
   --muted and --accent2 stay at their brand values for non-text uses
   (borders, small decorative marks) where the 3:1 UI-component
   threshold applies instead. See README for the numbers. */
