1/**
2 * UTM tracking condiviso (HubSpot + Forminator).
3 *
4 * Cattura i parametri UTM dalla URL, li conserva in un cookie e li propaga ai
5 * link interni; espone setHSFormValues() per i form HubSpot (chiamata in
6 * onFormReady) e popola automaticamente i campi nascosti dei form Forminator.
7 *
8 * La configurazione (dominio e nome del cookie) arriva da PHP via
9 * wp_localize_script -> window.namHubSpotUTM. Adattato da docs/utms-js.txt.
10 *
11 * @since 1.0.0
