-
-- **Host:** `127.0.0.1`
-- **Port:** Check `.docker/docker-compose.yml` for the mapped port (usually 3307+)
-- **Credentials:** Read from `.docker/.env`:
-  - `DB_USERNAME`
-  - `DB_PASSWORD`
-  - `DB_DATABASE`
-
-```bash
-docker exec -it dw-<project-name>-db mysql -u root -p<password> <database>
