+Runtime hook: preload onnxruntime native DLLs before any Python import can fail.
+
+The problem:
+  onnxruntime_pybind11_state.pyd imports onnxruntime.dll, which during its
+  DllMain calls LoadLibraryW("onnxruntime_providers_shared.dll") using the
+  standard Win32 search order (SetDllDirectory / PATH), NOT the
+  AddDllDirectory search order.  In a one-file PyInstaller bundle the DLLs
+  land in _MEIPASS/onnxruntime/capi/ — a subdirectory that is NOT covered by
+  either SetDllDirectory(_MEIPASS) or PATH in a clean deployment.
+
+The fix:
+  Load both DLLs by absolute path with ctypes.WinDLL() here, before Python's
+  importlib ever tries to load the .pyd.  Once a DLL is loaded into the
+  process the Windows loader returns the cached handle on any subsequent
+  LoadLibraryW call for the same module name, so ORT's internal lookup
+  succeeds regardless of search-path issues.
