"""Node / swarm mesh — faithful VISUALIZATION of the lab, not a distributed system.

Mirrors microfactory-lab's `zellij-layout.kdl`: a Chief Engineer hub coordinating
capability nodes. Only the 3D Print node executes real work (the core loop);
the others render as mesh context / available capacity. No FileBridge IPC, no
pi-link, no six live processes (that was the Kaggle failure surface).
