Reverse-engineered reimplementation of 3D Pinball for Windows - Space Cadet from k4zmu2a/SpaceCadetPinball (MIT), upstream cb9b7b8, vendored rather than submoduled so local patches are just edits. - CMakeLists: stop hard-setting CMAKE_OSX_ARCHITECTURES so the documented -D override works; brew's SDL2 is arm64-only and universal linking failed. - gitignore original .DAT/.MID assets, which are not ours to redistribute. - CLAUDE.md: build line, upstream deviation, and where game data goes.
