• Overview — request flow, top-level diagram, layers.
• Crates — every workspace crate and its responsibility.
• Clustering & multi-realm — how a single deployment hosts N realms with cross-realm matchmaking and transfers.
• Messaging & NATS — subjects, queue groups, JSON envelope with hex-encoded packet bodies.
