PROFILES → group optional services (e.g. only start "debug" tools when wanted):
docker compose --profile debug up
OVERRIDE files → docker-compose.override.yml auto-merges (dev overrides);
or -f compose.yml -f compose.prod.yml for environment-specific configs
SCALING → docker compose up --scale worker=3 (run 3 instances of a service)
NAMED VOLUMES & NETWORKS → declare and configure them at the top level
