# ── Production-like Local Stack (ADR-029) ──────────────────────────
# Creates a production-like stack locally.
# PostgreSQL is NOT exposed to the host — access only via Docker network.
#
# For actual production deployment (Render), use the dashboard or
# render.yaml. DATABASE_URL is injected by the PostgreSQL addon.
#
# Usage:
#   docker compose --env-file .env.production up -d

  # Port 8883 (MQTTS, TLS) expuesto al host para firmware.
  # Port 1883 (MQTT) NO se publica al host — solo accesible dentro de la
  # red Docker (ISSUE-075/PR-A): el backend bridge usa MQTTS en 8883.
