/* =====================================================================
   VRANGR — Secure operational intelligence
   Brand system v5 "Blackfile". Dark, severe, institutional.
   1980s/1990s U.S. government clandestine-operations atmosphere built
   from documents, terminals, redaction bars, routing lines, and stamps.
   The existing corner-bracket logo is preserved, not redesigned; its
   crop-mark geometry drives frames, panels, and the wordmark lockup.
   Dependency-free. One stylesheet drives every page.
