/* Neurigraph Console, aiConnected brand.

   Intent: an operator moving through a mind. Every screen answers "what does
   this memory know, what is awake right now, and how does it connect?"
   Depth: dark mode is navy depth with surface shifts and hairlines; light mode
   is ice white with soft shadows. Signature: the firing path. A signal travels
   from the core outward, in the ambient synapse field, the Cortex map, the
   4-hop retrieval trace, pathway graphs, and every activation (tier) mark. */

   Personas are people: each carries its own color (--p-color) as a ring and a
   faint wash, never as a fill that competes with the signal blue. Chat keeps
   the firing-path signature: a speaking persona's orb pulses outward, and a
   reply streams in behind a signal caret. */
