/*
 * CIS400 reveal.js theme: Cybersecurity & AI
 * Syracuse Orange (#F76900) + Navy (#000E54), with a "signal" cyan accent
 * for security/AI emphasis. Light variant: white slide background,
 * solarized-light code blocks.
 *
 * This theme is shared by every deck under ../../slides/. Edit it here and
 * every deck updates. Classes are generic (title-slide, section-divider,
 * big-point, two-col, callout, playground, footer) so decks stay portable.
