Notes on Atomic Commits

Each commit should:

• Focus on a single concern
• Be independently testable
• Not break the build
• Include related tests and documentation
• Have a clear, descriptive message

The commits above represent logical units of work that could be reviewed, tested, and potentially reverted independently.
