Add subtle directional arrows on a few edges to imply orchestration and handoffs. Behind the network, a translucent layered “state board” panel (like a glass dashboard) shows minimal icons: a document, a checkmark, and a message envelope, suggesting shared state, validation gates, and protocol messaging.

Use soft shadows and gentle bloom for depth, with plenty of negative space so the structure reads instantly at small size.
