/* ============================================================================
   HUMAN & MACHINE — the flagship editorial desk template.
   Tracks the interface between human intent and machine logic.
   Locked to the Non-Fiction Broadsheet (.mode-frontpage): white ground, red Pulse.
   Reuses broadsheet.css tokens (--display/--serif/--label/--pulse/--ink/…).
   Four zones: THE QUERY · THE ORACLE OUTPUT · THE EDGE ANALYSIS · THE ABYSS ECHO.
