    # No proxy source: this build defeats every app-dir plant (System32 crypto pre-load; DXGIDisplays
    # not loaded in VR mode; UnityPlayer self-references and fail-fasts on a stub). With no anti-cheat
    # in-process, the vector is plain injection -- tools/launcher/launcher.exe suspended-launches
    # RecRoom.exe and LoadLibrary-injects this DLL before first instruction. DllMain (dllmain.c) starts
    # the hook thread. No exports needed.
