- Set CMAKE_OSX_DEPLOYMENT_TARGET and CMAKE_OSX_ARCHITECTURES before project() so they propagate to all FetchContent dependencies (SDL3, etc.) - build.sh: native mac release builds universal binary, detects and rebuilds single-arch libsodium, verifies with lipo, exports MACOSX_DEPLOYMENT_TARGET; dev build uses correct build/mac directory - fetch-libsodium.sh: build arm64 and x86_64 separately then merge with lipo on native macOS; fix sha256sum unavailable on macOS (use shasum)
