 `chasqui` (Quechua: *Inca relay messenger*) is the networking layer: peer discovery (UDP + Kademlia DHT), relay/dcutr/autonat for NAT traversal, and authenticated transport over the `card` identity. Channels and capabilities are expressed as typed cards; no TCP/IP assumptions leak into the apps above it.
