- **Layer 3** (tasks): No matplotlib, can use pandas/numpy
- **Layer 4** (workflows): Can use matplotlib, orchestrates tasks and primitives

Code Style
----------

- Use Google-style docstrings
- Include type hints for all functions
- Follow PEP 8 (enforced by ruff)
- Run ``ruff check`` and ``ruff format`` before committing

Testing
-------

- Write tests for new features
- Ensure all tests pass: ``pytest``
- Aim for high test coverage
