+// ============================================================================
+// ANSLibsLoader — Centralized dynamic library loader for ANSCENTER
+//
+// Consolidates all runtime DLL loading:
+//   - ONNX Runtime (via EPLoader)
+//   - TensorRT / cuDNN / CUDA (via NvDynLoader)
+//   - OpenCV (via CvLoader)
+//   - OpenVINO + TBB (via OvLoader)
+//
+// USAGE
+// -----
+//   // At application startup:
+//   ANSCENTER::ANSLibsLoader::Initialize();
+//
+//   // At application exit (after all engine objects are destroyed):
+//   ANSCENTER::ANSLibsLoader::Shutdown();
+//
+// EXPORT MACRO
+// ------------
+//   ANSLIBS_API replaces both ANSCORE_API and ENGINE_API for loader classes.
+//   Define ANSLIBSLOADER_EXPORTS when building ANSLibsLoader.dll.
+//   All other projects importing from ANSLibsLoader get __declspec(dllimport).
