/*
  Design system di novior.it, fase 1 (pagina "in arrivo"): sobrio e istituzionale, con i colori del logo (02/10/2026):
  il blu notte del fondo, il ciano e l'azzurro del nastro, il blu delle pieghe. Il tema segue il browser, chiaro o
  scuro (decisione dell'utente); il logo, che per ora è solo un JPEG con il suo fondo scuro, sta in un riquadro
  arrotondato nei due temi. Il filo sfumato sopra l'intestazione riprende il nastro ed è decorativo.
  Token su :root per il tema chiaro; tema scuro con prefers-color-scheme e con [data-theme="dark"].
  Solo font di sistema: nessun file di font, nessuna risorsa di terzi (la CSP di produzione è 'self').
  Contrasti verificati il 02/10/2026, tutti oltre WCAG 2.2 AA (4,5:1): chiaro ink 16,1 · muted 6,6 · accent 6,0 (5,4 su
  accent-soft) · pulsante 6,4; scuro ink 17,8 · muted 8,9 · accent 10,4 (7,8 su accent-soft) · pulsante 10,0;
  etichetta PreProd 8,8 e 9,5.
