/* ST SAFE TRAVEL — Travel-risk atlas
 *
 * Concept "Atlante": una carta nautica chiara. Carta grigio-nebbia con graticola
 * (reticolo di meridiani/paralleli a filo), accento blu oceano e un solo segnale
 * arancio-bussola per minaccia e allerta. Le schede minaccia sono fascicoli
 * (dossier) con segni di registro agli angoli e un timbro tratteggiato per il
 * livello Basso/Medio/Alto. Header chiaro con scala metrica in basso.
 * Nessun gradiente decorativo, nessun glow, nessuna nuvola, nessuna emoji.
 *
 * Font (solo self-hosted, /css/fonts.css): Instrument Serif (display), DM Sans (testo),
 * IBM Plex Mono (etichette, punteggi, numeri).
 *
 * Contrasti (WCAG): ink su carta 14.2:1, muted su carta 5.6:1, oceano #0b6e99 su carta 4.9:1
 * e su card 5.4:1, bianco su oceano-scuro #085a7e 7.6:1, segnale #b93a0a su card 5.9:1,
 * "Model" ink su header 15:1, "Vault" #0b6e99 su header 5.4:1.
