/* ============================================================================
   ERA GATE — style.css · Proposta grafica sito marketing v0.1
   ----------------------------------------------------------------------------
   Struttura pensata per il co-sviluppo:
   1. Design token (variabili CSS) — QUI si cambia il brand, non nel resto
   2. Base e utilità
   3. Componenti (bottoni, card, badge)
   4. Sezioni della pagina, in ordine di apparizione
   Convenzioni: classi tipo BEM semplificato (.blocco, .blocco-elemento),
   niente framework, mobile-first con breakpoint a 720px e 980px.
