+-- hand-maintained: `name` is the single atomic segment with the namespace
+-- beside it, `maintainers` stays here (mcpp.toml has no such key), and the

+-- carried on this file.
+--
+-- NO `macosx` TABLE. The CPU backend is AVX2 (`_simd_math.h` includes
+-- `<immintrin.h>`), so the package's own `platforms` names linux and windows
+-- only; 0.3.1 withdrew the macOS claim rather than publishing a tarball that
+-- cannot compile on Apple silicon.
