/*
 * Referral Gift popup.
 *
 * Design reference is the retired Eid modal: darkened blurred overlay, artwork
 * on one side and copy on the other, stacked on mobile, gold close control.
 * The palette is not carried over. That modal was near-black and bright gold;
 * this one uses the same emerald / cream / muted-gold tokens as the carousel so
 * the two promotional surfaces read as one system.
 *
 * Decoration is CSS only. The original used three full-screen <canvas> particle
 * engines with their own rAF loops; the announcement bar already proves a
 * two-layer radial-gradient drift is enough, costs nothing, and is trivial to
 * disable under reduced motion.
