+hook_path.py — PyInstaller runtime hook for Website Checker.
+
+Executed by the PyInstaller bootloader before any Python code runs.
+Prepends the bundle's _internal/ directory (where python3xx.dll lives)
+to the Windows PATH so that LoadLibrary() can find the VC++ runtime DLLs
+(vcruntime140.dll, msvcp140.dll, etc.) that python3xx.dll depends on.
+
+This resolves the error:
+  "Failed to load Python DLL ... python3xx.dll.
+   LoadLibrary: The specified module could not be found."
+
+Without this hook the DLL is present in the bundle but Windows cannot
+satisfy its own import chain because the VC++ DLLs are not on PATH.
