     bright line); it is --brand-green from 2026-08-10. Green on navy is
     1.68:1, so the rule deliberately does not read as a line against the bar
     above it — what you see is its 9.4:1 edge against the white below, i.e. a
     navy bar that ends in a green lip rather than a bar with a stripe under
     it. That is a look, not a bug; it is only decorative either way (1.4.11
