/*
 * Roft Builder: základní prvky (úkol B6).
 * Nadpis, text, obrázek, tlačítko, ikona, ikona s textem, seznam s ikonami, oddělovač, mezera, HTML kód,
 * sociální sítě, obrázková karta. Výchozí vzhled; nastavení prvku (.rb-ID …) ho vždy přepíše.
 *
 * Proměnné, které nastavují controly na obalu prvku (.rb-ID):
 *   --rb-button-duration, --rb-image-duration, --rb-icon-duration, --rb-icon-list-duration,
 *   --rb-social-duration, --rb-image-box-duration  délka přechodů při najetí
 *   --rb-divider-style, --rb-divider-weight, --rb-divider-color (na .rb-divider), --rb-icon-list-gap,
 *   --rb-icon-list-divider, --rb-social-color (barva sítě).
 * Barvy a typografie navazují na globální styly (--rb-c-primary, --rb-t-button-*).
