/* AB Toolkit — quizzes, checklists, lead forms.
   Mirrors the theme's DESIGN.md system: Primary #1E5A8A / Accent #F2A93B,
   Playfair Display headings over Inter body, 8px radii.

   The `-ink` variants are deepened for WCAG AA: the spec's Success, Error and
   Accent hues are fine as fills under dark text, but fail 4.5:1 as small text
   on white (or under white text), so text and chips use the ink variants. */
