#
# Spins up 2 voters + 1 witness using public images from ghcr.io.
#
# Usage:
#   docker compose -f deploy/docker-compose.cluster.yml up -d
#   # Wait ~10s for election, then:
#   curl http://localhost:7438/v1/cluster   # voter1
#   curl http://localhost:7448/v1/cluster   # voter2
#   # Whichever returns role=Leader is your write target.
#
# Tear down:
#   docker compose -f deploy/docker-compose.cluster.yml down -v
