1/*
2 * Eventi ecommerce (GA4-style) verso il dataLayer di Google Tag Manager.
3 * File indipendente, non tocca in alcun modo l'evento onboarding esistente
4 * (quello resta in base_onboarding.twig / ty_confirmed_nonfood.twig).
5 *
6 * Tutti gli eventi sono attivi solo se window.gtmMarketingEnabled === true,
7 * impostato nei template in base a attivita.getMarketing() (colonna has_marketing).
8 *
9 * Ogni funzione e' avvolta in try/catch: un errore qui non deve MAI
10 * interrompere il codice chiamante (checkout, add to cart, ecc.).
