# =============================================================================
# Cleans up the Docker system to reclaim disk space.
#
# Removes:
#   - All stopped containers
#   - All networks not used by at least one container
#   - All unused images (not just dangling ones)
#   - All build cache
#
# Preserves:
#   - All volumes (to protect application data like Redis, PostgreSQL, etc.)
#
# Usage: make clean  OR  sudo bash scripts/docker_cleanup.sh
# =============================================================================
