/*
 * style.css — Funnel Volpe Miliardaria (SYN-11)
 *
 * Redesign tipografico rev.2 (board 2026-07-22):
 *   • Font heading cambiato: Syne → FRAUNCES (serif display editoriale, "old money",
 *     alto contrasto + optical sizing) — coerente con brand "finanza sofisticata".
 *   • Sistema a 3 voci:
 *       - Fraunces      → heading + KPI/cifre   (--font-heading)
 *       - IBM Plex Sans → body / UI             (--font-sans)
 *       - IBM Plex Mono → eyebrow, label, meta  (--font-mono)
 *   • Layout: sezioni testuali su GRIGLIA EDITORIALE a 2 colonne (intestazione a
 *     sinistra + contenuto a destra) per riempire lo spazio ed evitare i vuoti
 *     orizzontali sulle viewport larghe. Ritmo verticale più compatto.
 *
 * Palette invariata (brand bible §3): editoriale "old money" — crema caldo,
 * verde bosco, blu notte, accento oro sobrio. Nessun colore fluo.
