## Notes

- Both commits used minimal commit messages (`.`), which is not ideal for future reference
- The changes are substantial and well-structured despite terse messages
- These commits should be considered atomic units that work together
- The refactoring (commit 1) provides the foundation for the documentation (commit 2)
