Drop one master image, name the app, forge the button. Out comes a ZIP of icons only — eight correctly-named image files. No manifest, no service worker; those live with your app.
1 Master image
2 App name
iOnly used to name the ZIP so you can tell bundles apart — e.g. Birth. The icons themselves carry no name; that lives in your app's manifest.
Just labels the downloaded ZIP. Optional context, no effect on the images.
