/*
 * REGOLA D'ORO: gli stili di base (corpo, titoli, link, pulsanti) sono
 * scritti dentro :where(), che ha specificita' ZERO. Qualunque regola di
 * Elementor (impostazioni globali del sito, singolo widget, sezione) li
 * scavalca sempre, senza !important e senza "rompere" le impaginazioni.
 * Il tema decide solo cio' che nessun altro ha deciso.
 *
 * Tutti i valori arrivano da variabili CSS --rsn-studio-*: scritte su
 * :root dal Customizer (inc/customizer.php) e, con Elementor, sul <body>
 * dalla scheda "Thema RSN" delle Impostazioni sito, che quindi prevale.
