/* ================================
   GRAPH COMPONENT · Cytoscape
   Scope: .hi-graph-*
   ================================
   Reutiliza del design system: --hi-paper, --hi-ink, --hi-ink-mute, --hi-rule,
   --hi-mono, --hi-serif, --hi-sans, --hi-accent, --hi-paper-warm.
   Variables nuevas (este archivo): --hi-graph-bg, --hi-graph-toolbar-bg,
   --hi-graph-toolbar-fg, --hi-graph-sidebar-w, --hi-graph-accent,
   --hi-graph-shadow, --hi-graph-shadow-lg, --hi-graph-radius.

   Decisiones:
   - Toolbar navy (#1a202c) en vez de --hi-ink (marrón): el grafo es una
     "zona foco" distinta, y el navy contrasta mejor con el acento naranja.
   - --hi-graph-accent (#ed8936) es la versión saturada de la familia gold
     (#d9bd86). --hi-gold no leía sobre el toolbar oscuro.
   - Sombras con tinte navy para casar con la temperatura del toolbar.
   - El body usa flex:1 en vez de height:calc(100% - 44px) para evitar el
     número mágico y adaptarse si el padding del toolbar cambia. */
