// Package overlay is the private network: its names, its manifest, the peer graph and the generator of each node's
// network configuration. It is the own package of the module mesh-wireguard, which holds the seat the-private-network
// (novox/hq ADR 0636 §6); the node-engine imports it to compose the module for a node, and the layout of the value the
// seat provides is the seat's contract in mesh-connectivity-contracts (ADR 0634 §1).
