"""
Example seed for the shared dcntrlized database.

Seeds run automatically after migrations complete, via the compose 'seed'
service: database/seeds is mounted read-only into a python container and every
*.py file here is executed in sorted order. Connection settings come from the
PGHOST/PGPORT/PGUSER/PGPASSWORD/PGDATABASE environment variables set by that
service (psycopg2.connect() reads them implicitly).

Keep every seed idempotent: it re-runs on every `docker compose up` (use
ON CONFLICT DO NOTHING / IF NOT EXISTS style upserts, stable uuids, ...).
