+/* JNI bridge — connects Java NativeBridge to Rust C ABI
+ * Compile: gcc -shared -fPIC -I$JAVA_HOME/include -I$JAVA_HOME/include/darwin
+ *   -I native/include -o libcraftlabs_jni_bridge.so jni_bridge.c -L. -lcraftlabs_auth_core
+ *
+ * Then: java -Djava.library.path=. ... loads both libraries.
+ * Or rename the output to craftlabs_auth_core and load it directly.
