       measured 2.41:1 against --bg, failing WCAG AA for the small uppercase .eyebrow
       text it was applied to. It passes comfortably on dark surfaces, so it is kept
       there rather than discarded.

       --accent is checked against every light surface it can land on, not just --bg:
       --bg 5.04:1, --surface 5.26:1, --section-muted 4.55:1, .answer-box 5.03:1.
       --section-muted is the binding constraint. --accent-on-dark: 7.67:1 on --dark,
       5.24:1 on --brand. */
