 * Optional integrations with popular third-party plugins.

 * so the file is safe to load on a vanilla site.
 *
 * Currently supported:
 *  • WooCommerce  — orders, product changes, refunds
 *  • ACF          — field group + field value updates
 *  • WPForms / Gravity Forms / Contact Form 7 — submissions
 *  • Yoast SEO / Rank Math — option changes
 *  • Elementor / Divi / Gutenberg — template & widget saves
 *
 * @package ActivityPilot
