/* ===================================================================
   ZONE IT & TELECOM — signal build
   -------------------------------------------------------------------
   DIRECTION OF FLOW: along the path, left to right and downstream.
   Every animation here obeys it — packets travel right through the
   trace dividers, pulses run down the topology, card highlights draw
   from the left edge, the link rail fills top to bottom. One network,
   not a pile of separate effects.

   PALETTE: the mandated Zone Group blue system. Deep navy ground,
   raised navy surfaces, one working blue for action and a lighter
   blue reserved for connections and data. Nothing glows for the sake
   of glowing — this company installs real cable in real buildings.
