/* Three-dot breathing loader shared across miniapp paginated lists
 * (inbox, channel/DM message-list upward pagination, channel threads).
 * Mirrors web's --animate-activity-breathing cadence (1.4s ease-in-out)
 * with a staggered 0.18s delay per dot for a calm wave effect.
 *
 * No styleIsolation: relies on global app.wxss design tokens the same way
 * sheet-header / message-list skeletons do. */
