// --probe-dpi: the process DPI awareness that nx2navi.manifest declares, and what the primary monitor reports under it.

|
// A DPI-unaware process gets every window and monitor size scaled down by the display scale and its output stretched
|
|
// back up by Windows; the probe fails unless the process is per-monitor aware (v2). Needs no game files and no GPU.
