// ANSGpuFrameRegistry.cpp — Process-wide singleton, compiled into ANSCV.dll.
//
// On Windows, header-only singletons (static local in inline function) create
// separate instances in each DLL. Since gpu_frame_attach() runs in ANSCV.dll
// and gpu_frame_lookup() runs in ANSODEngine.dll, we need a single shared
// instance. This file:
//   1. Defines resolveProcessWide() which owns the canonical singleton.
//   2. Exports a C function so other DLLs can find it via GetProcAddress.
