- Unified resolution to 1280x720 (same as D3D12) - Added XCEngine Logger integration for debug output - Added screenshot capture at frame 30 (glReadPixels -> PPM) - Added run.bat test script - Added compare_ppm.py for screenshot comparison - Added GT.ppm reference image - Added README.md documentation - Updated CMakeLists.txt to link XCEngine library Test: OpenGL rendering test passed (screenshot comparison 100% match)
