+# Local dev Postgres connection string — matches docker-compose.yml's `db`
+# service (POSTGRES_USER/POSTGRES_PASSWORD/POSTGRES_DB there must stay in
+# sync with this). Copy this file to `.env` (gitignored) and adjust if
+# needed.

+# The hostname `db` only resolves from containers attached to the
+# `asset-license-mgmt-net` Docker network that docker-compose.yml creates —
+# see CLAUDE.md's "Môi trường" section for the exact docker compose/run
+# commands used to run the app and tests on this Windows host.
