   HIVE — Atrium.
   Agents are colleagues with a job description, so the room should feel like
   a room: humanist type, generous spacing, a plum that carries agent identity,
   and semantic colour kept strictly separate from the accent.

   Dark is designed, not inverted — see the token block below.
