/* CSC System — site design system.
 *
 * A ground-up replacement for the previous layout, which was derived from the
 * ZazaPass template: tilted fake-dashboard mock, sparkline "metrics", grid
 * overlays, "fragmented" panels and mono micro-labels. None of that is here.
 *
 * The language instead: deep navy field, a single luminous accent, wide
 * horizontal rules instead of card soup, large confident type, and real content
 * hierarchy. The logo mark is the only decorative element.
