// ships Node-API prebuilds for every packaged platform, and Node-API addons
// are ABI-independent (verified under electron 43 / NODE_MODULE_VERSION 148).
// These tests pin the prebuild selection logic that replaced the historical
// `npx node-gyp rebuild` spawn plan (whose win32 .cmd/shell quirk broke the
// v3.8.47 tag build — that entire code path is now gone).
