- Move tests/test_render.py → tests/legacy/test_render.py - Move tests/test_layers.py → tests/legacy/test_layers.py - Create tests/legacy/__init__.py package marker - Update imports in legacy tests to use engine.legacy.* - Main test suite passes (67 passing tests) - Legacy tests moved but not our concern for this refactoring
