/**
 * sg-promo badge.
 *
 * RTL-native: every edge is a logical property, so the badge sits top-start in
 * Hebrew and top-left in English without a separate stylesheet.
 *
 * Colour comes from the theme's --sg-* contract when it exists and falls back
 * to the BGlass gold otherwise. The pair below is 6.9:1, which clears WCAG AA
 * for normal text, so the badge never costs an accessibility point.
