   Corpus Constellation — instrument styles
   ==========================================================================
   Namespaced beneath .archive-instrument--constellation. Consumes only the
   foundation tokens. Register colours are defined here as custom properties
   so the host can retune them; colour is never the sole carrier of meaning
   (register and status are always present as text in the dossier, legend,
   index, and exports).

   One deliberate exception to "amber emphasis / green traversal": nothing.
   Green appears only on the active journey path and live signals.
