# Project Guidelines

## Commits
Follow GNOME style: Summary <72 chars, imperative, no period. Body with bullet points for changes.

## Code
- Classes for modularity, private attrs/methods (_prefix).
- Avoid redundancy (e.g., single strip() calls).
- Encapsulation over public access.

## Testing
- Dry-run first, check logs/counts vs. Thunderbird.
- Verify no duplicates or errors.

## Security
- Never commit .env; use .env.example.
- Private credentials, no hard-coded URLs.
