What does STYLE.md say about voice and about line length?
final reply
STYLE.md says:

- **Voice:** Use the active voice. It gives the example of writing "the service validates the token" rather than "the token is validated".
- **Line length:** Keep prose lines under 100 characters, and wrap long sentences.
