# feature-container-runtime-contract — local infrastructure override
#
# Merge with base (and optionally dev):
#   docker compose -f docker-compose.yml -f docker-compose.local.yml up
#
# Local intent:
#   - Starts a local PostgreSQL database for integration testing without Testcontainers.
#   - Wires the app environment to point at the local DB.
#   - Keeps read-only filesystem and memory limits from the base compose.
#   - Does NOT expose the DB port publicly; app and db communicate on the
#     internal `caskeleton-local` network only.
