//! Windows only: mark `craft-anything-cli.exe` DPI-aware (an application manifest), so window
//! pictures (`native_window_capture`) and screen coordinates are in real pixels at any display
//! scaling. On every other target this does nothing. A missing resource compiler is a warning,
//! unless `CRAFT_ANYTHING_REQUIRE_WINRES=1` (the release workflow) makes it an error.
