+/**
+ * Pin every Android module to the NDK this project declares above.
+ *
+ * Most native modules already honour rootProject's ndkVersion, but a module that has an
+ * externalNativeBuild and never sets ndkVersion on its android extension silently falls back to
+ * whatever NDK the Android Gradle Plugin defaults to. That default is a different version than the
+ * one we pin, so the build then demands an NDK nobody asked for and fails at configuration time
+ * with "[CXX1101] NDK at .../<version> did not have a source.properties file" if it isn't installed
+ * (or is a partial install). react-native-nitro-cloud-uploader is one such module.
+ *
+ * Setting it here keeps every module on a single NDK regardless of what each one declares.
