Prepare images for use as custom app icons (macOS 26.0+). #### This shortcut prepares an icon (eg. exported from Icon Composer) for use as a custom app icon on macOS 26. The input image is resized to 824×824 px, then given 100 px of padding on all sides. The output is a 1024×1024 px PNG file that matches the visual style of stock macOS apps.  _Note that this is intended to be used with a full-size squircle as shown above._
