+// cxx-qt 0.8.1's PluginType::Dynamic emits a QQmlEngineExtensionPlugin whose
+// constructor only anchors qml_register_types_NovaStats with `volatile auto X = &X`
+// (linker-keep, not a call), and the qmltyperegistrar static init doesn't call it
+// either. Net effect: types never register, NS.* stays undefined in QML. Workaround:
+// call it ourselves at .so load time. The function is mangled (returns void, no
+// extern "C"), so go through #[link_name] using the itanium-mangled symbol seen in
+// `nm libNovaStats.so | grep qml_register_types`.
