    // Use the software (CPU raster) renderer.
    //
    // This app is a pure 2D text / UI — there are no 3D effects, shaders or
    // GPU-only features that would justify a GPU backend.  The software
    // renderer eliminates ALL GPU swap-chain resize artefacts (black/white
    // flicker when dragging the window border) without any platform-specific
    // hacks, while still delivering smooth performance for a simple UI.
    //
    // Note: GPU backends (D3D11/OpenGL) in the threaded render loop expose a
    // fundamental Windows limitation: the DWM compositor fills newly-uncovered
    // pixels with black (expand) or the GDI background brush (shrink) between
    // the moment the OS resizes the window and the moment the GPU presents the
    // next frame.  There is no clean fix without serialising the render loop
    // (which causes stutter) or installing a native WndProc hook (fragile).
