/* ==========================================================================
   TECHDZAMSA — DESIGN SYSTEM
   --------------------------------------------------------------------------
   The system is derived from the TechDzamsa mark: a portrait held inside a
   bracketed technical frame, wired to two processor pads by copper traces.

   Four primitives carry the whole interface:

     BRACKET   — four corner marks that frame a subject instead of boxing it.
                 The mark's own device. Used on stages, plates and CTAs.
     NOTCH     — a chamfer on the top-left and bottom-right corners. Every
                 angled edge in the interface runs on that one diagonal.
     TRACE     — orthogonal hairlines with right-angle elbows and square
                 terminal pads. Lines that route, never lines that decorate.
     NOTATION  — small mono labels that let the interface read as equipment.

   Copper is heat: it marks what is active, current or addressable, and
   nothing else. Teal is reserved for live state. Everything else is graphite.
