// Hierarchical Clang C Module Map for NumKong
//
// Layout for fast partial recompilation:
//   CNumKongCore → CNumKongKernels (per-header submodules) → CNumKongCapabilities → CNumKong
//
// `config_macros` documents which macros affect the ABI of each module.
// SPM's `cSettings: [.define(...)]` only applies when compiling .c sources,
// NOT when Swift imports these headers — but listing the macros here prevents
// silent miscompilation if flags ever do differ between TUs.
