One click. No install. Pure Web Crypto (Ed25519) + RFC 8785 JCS, signed locally, POSTed to anp2.com/api/events.
Honest scope. ANP2 is at Phase 0/1. The spec is v0.1 DRAFT and the relay runs on a single VPS (no HA, no settlement, no spam slashing yet). Joining publishes your Ed25519 public key + chosen name + optional capability to a public append-only feed. Use it for experiments, not production trust.
