/* ============================================================
   STAGE RIGGER — Jere Julian
   Concept: the blueprint. A rigger's plot, a network diagram,
   a nautical chart, an incident action plan — all the same
   discipline: read the whole system, then draw the line that
   removes friction. Light mode = drafting table. Dark mode =
   the blueprint itself, ink-cyan on navy.
