/*
 * GGMB Brokers — foglio di stile del sito pubblico.
 *
 * Il sito è statico (HTML, CSS e JavaScript vanilla) e non dipende da CDN:
 * font, icone e libreria di scroll sono vendorizzati sotto `assets/`.
 *
 * Organizzazione del file:
 *   1. Font e design token (colori, tipografia, spaziature, movimento)
 *   2. Temi di sezione (inchiostro / avorio / pietra)
 *   3. Base, reset e accessibilità
 *   4. Primitive di layout e tipografia
 *   5. Componenti condivisi (pulsanti, link, etichette, header, menu, footer, dialog)
 *   6. Sezioni della home
 *   7. Pagine interne (soluzioni, contatti, documenti, reclami, privacy, 404)
 *   8. Sistema di animazione (reveal, split del testo) e preferenze di movimento
 *
 * Direzione artistica: un mondo quasi monocromatico (inchiostro blu-nero e avorio
 * caldo) in cui l'unica fonte di colore è la stella del logo. I cinque colori
 * delle sue sfaccettature compaiono solo come accenti precisi, mai come
 * riempimento di grandi superfici: così il colore resta prezioso.
