/* ============================================================
   Helicon Defense — v5 additions (loaded AFTER styles.css)
   Implements the P1 "one primary navigation" masthead, one semantic
   breadcrumb, and the figure block (SVG primary / PNG fallback /
   vertical stack below 768px). Brand tokens are inherited from
   styles.css — no new colours, no new typefaces.
