/* The ONE public stylesheet (spec §5.6, T58). Neutral palette only: #1E293B (ink) and #2563EB

   every other value on this page derives from them - rgba() tints, white, and nothing else.
   Anchor's navy is a leak and noAnchorNavy's scan covers this file. No emoji, no icon font, no
   webfont fetch, no url() of any kind, no @import: the public pages make zero third-party
