 History currently uses brief German titles; shift to imperative, scoped summaries such as `feat: add PDF mailer` or `fix: guard MQTT reconnects`. Keep unrelated updates out of the same commit and exclude artifacts like `node_modules/` or `target/`. Pull requests should explain the motivation, link issues, note config or data-seed impacts, and attach screenshots or screencasts when Vaadin views change. List manual verification steps and flag any migrations or bundle adjustments for reviewers.
 
 ## Security & Configuration Tips
-External service credentials for MongoDB, SMTP, and MQTT belong in environment variables or a developer-specific `application-local.properties` kept out of version control. Document default ports and topics when touching `MqttConfig` or Zeroconf publishers so ops can replicate environments. For two-factor flows, keep shared secrets in secure storage and avoid logging codes during development.
