  # Three harness-only patches to wnd so it runs fully offline / in
  # sandboxes that block outbound + kernel keyring:
  #   1. discovery-env: honour $WHITENOISE_DISCOVERY_RELAYS so we can
  #      point wnd at our loopback relay instead of the baked-in public
  #      set. Without it wnd exits with NoRelayConnections.
  #   2. mock-keyring: honour $WHITENOISE_MOCK_KEYRING so wnd uses the
  #      integration-tests mock keyring store when the kernel keyutils
  #      syscalls are blocked (common in containers / CI).
  #   3. defaults-env: reuse the same env var so `Relay::defaults()`
  #      (what `create-identity` stamps into the new account's NIP-65 /
  #      inbox / key-package lists) points at the loopback relay too.
  #      Without it every account wnd creates carries damus.io /
  #      primal.net / nos.lol, and every later activate / publish burns
  #      connection budget on unreachable sockets — enough to break the
  #      account-inbox subscription plane and drop kind:1059 delivery.
