/* YAOQIAN — money-tree red & gold theme.
 * Visual identity: deep lacquer red ground, brushed-gold rules, hanging
 * coin ornaments, and a vermilion seal stamp (印章) as the accent mark.
 * Layout is an asymmetric "scroll" composition, deliberately unlike the
 * centered-card layouts of earlier projects. */
