   18. LIVE DEPOT PIPELINE (index.html "What AI Depo is" schematic)
   Append-only. Makes the data-flow schematic a continuously-animating,
   always-on ambient pipeline: bright packets of light travel along the
   connectors (looping stroke-dashoffset) while the stage nodes + depot light
   up / pulse in sequence (data -> systems -> tools -> in production).

   The diagnosis: the old single .flow-line per path used a faint gradient
   stroke with a sparse 8/16 dash that read as static, and nothing lit the
   stages. Here each connector keeps a dim base "rail" plus an overlaid
   bright "packet" that loops forever, and every stage pulses on a staggered
   ambient loop. No JS required; reveal/.in does not gate any of it.
