# Targets SEED_RELAY_URL (default: .env RELAY_URL, else ws://localhost:3000)
# and refuses non-loopback relays. Ambient BUZZ_RELAY_URL/BUZZ_PRIVATE_KEY are
# ignored so an agent or shell session can never seed its real relay. Posts
# with SEED_PRIVATE_KEY (default: a fresh throwaway key) into a new open stream
# channel, or into SEED_CHANNEL if that key may post there.
#
# Every write (channel, root, replies, reactions) counts against the relay's
# 60 human messages/min, so writes are paced SEED_DELAY seconds apart (default
# 1.05): the default run takes ~3-4 minutes on a stock relay. Set SEED_DELAY=0
# when BUZZ_RATE_LIMIT_HUMAN_MESSAGES_PER_MIN is raised on the relay.
