 *
 * The status colours are not copied from the portal wholesale, because the two

 * panels; this site draws them on white and on tinted message strips, and three
 * of the portal's values fail contrast there — its amber measures 1.83:1 as
 * text on white. Every value below was measured against the background it is
 * actually used on, and the ratio is recorded beside it. docs/brand-system.md
 * carries the full table.
