Implement pytest-based testing framework with:
- Unit tests for configuration parsing and core generation logic
- Visual regression tests using perceptual image hashing
- Fixtures and test configuration in conftest.py
- Test documentation and usage guide
Visual tests generate reference images and compare new output against them
to catch regressions while allowing for minor anti-aliasing differences.
