A multi-resolution app.ico (16/24/32/48/64/128/256), Microsoft tile PNGs (44/71/150/310), an Apple .iconset folder for iconutil, an Xcode AppIcon.appiconset folder with all iOS sizes (40 to 1024), and Android mipmap folders for every density (mdpi to xxxhdpi) plus the 512×512 Play Store listing icon.
A square 1024×1024 PNG with transparency works best. Smaller inputs are upscaled, but the largest output sizes (1024 on iOS, 512 on Mac/Android) will look soft.
Run `iconutil -c icns macos/AppIcon.iconset` from a terminal on macOS to bundle the layers into a real .icns file.
