   (watch) to 3.76:1 (danger), so three of four fail even the 3:1 large-text
   bar and all four fail 4.5:1. The heading therefore uses a darkened variant
   of the SAME hue (all >=4.52:1 on white), and the true app colour is carried
   by the left border, where contrast rules do not apply to a decorative rule
   but the reader still learns the product's visual language. Do not swap the
   heading colours back to the raw app values on a safety page. */
