/* =========================================================
   ALPHA STRIKE — HERO NETWORK COMPONENT
   Version: 1.0
   Status: Active

   The Enterprise-page hero visual: a network topology diagram -
   server rack, workstation, laptop, router/switch and a cloud/
   web-technology node radiating from a central hub, connected by
   glowing lines with animated data pulses - sitting over the same
   perspective wire-mesh floor used on the Trading page, tying the
   two division pages into one visual family.

   Colour: the exact same locked accent used everywhere else on the
   site - ALPHA Yellow/Gold in dark theme, the locked v1.1 ALPHA
   Chrome (Steel/Silver) in light theme. No new colours.
