/**
 * fossjournaltheme — styles/index.css
 *
 * fossjournal OJS 3.4 theme: deep navy + gold academic system.
 * Overrides the standard OJS 3.4 front-end class names so every
 * rendered page (journal home, issue TOC, article, search, about…)
 * inherits the approved visual language.
 *
 * Tokens are injected per-journal via CSS custom properties:
 *   --fj-navy (base colour option, default #0B1D3A)
 *   --fj-gold (accent colour option, default #C8A961)
 * Derived tones stay fixed so the system reads as one brand.
