// StartOffline brings up a Node exactly like Start, but skips dialing the

// loop (see start's network parameter) — a real libp2p host and Bitswap
// stack, servable and fetchable, with no live network traffic. internal/ipfs's
// own tests reach start directly for this; StartOffline exists so other
// packages' tests (internal/pin's, for one) can drive a genuine, loopback-only
// Node end to end instead of a fake stand-in for the whole trustless
// pipeline. Not for production use: a Node with no DHT participation can
// never be found by anyone.
