Demo: Signet Sandbox

MC: nully0x

• One call provisions an isolated signet chain: bitcoind, a BIP325 block signer, and optional electrs, explorer, faucet, and LND.
• The call returns a connection bundle with every endpoint, macaroon, and TLS certificate.
• Three LND nodes on one private signet: fund each node, peer them, open a channel, pay an invoice, and close the channel.
• The failure path: what happens when a channel will not close.
• Teardown: a TTL deletes the environment, and the reaper takes the namespace with it.
• Discussion: regtest versus signet, and what an isolated chain cannot reproduce.
