#   * PostgreSQL 16 on 127.0.0.1:5440   (apt: postgresql-16; runs as the postgres user)
#   * Redis Stack on 127.0.0.1:6390     (docker: redis/redis-stack-server -- Redis + RediSearch + RedisJSON)
#   * plain Redis on 127.0.0.1:6391     (apt: redis-server, NO modules; only used to capture a failure)
# If you already have these, skip this script and set CM_PG_URL / CM_REDIS_STACK_PORT / CM_REDIS_PLAIN_PORT.
