/**
 * qTap Frontend Components
 *
 * Shared UI components for all qTap child plugins.
 * Designed for compatibility with:
 * - WooCommerce themes
 * - WordPress block themes (Twenty Twenty-Four, etc.)
 * - WordPress classic themes (Twenty Twenty-One, etc.)
 * - Custom themes
 *
 * Strategy: We provide our own complete styling via .kdc-qtap-* classes.
 * WooCommerce/block theme classes are added for enhanced compatibility,
 * but our styles work independently.
