  # Text colors here intentionally use palette steps (green/yellow/gray-700)
  # instead of the `text-success` / `text-warning` / `text-secondary` tokens
  # because the functional tokens drop below WCAG 1.4.3 4.5:1 on tinted
  # surfaces in light mode (~2.88:1 / 3.0:1 / 4.16:1). Each variant carries
  # a theme-dark: override so the dark-700 text doesn't disappear against
  # the dark-mode tinted surface. Local override only; revert once
  # we-promise/sure#1736 lands token-level fixes.
