Icons

PWARegistry looks at the Web App Manifest icons, fetches them, and classifies the reachable images. You do not inspect every raw manifest icon yourself.

Each full record has:

Field	Use
`application.icons.primary`	The icon for a normal listing. May be `null`.
`application.icons.maskable`	Maskable icons (for adaptive OS shapes).
`application.icons.monochrome`	Monochrome icons.
`application.icons.any`	Icons whose purpose is `any` (or unspecified).
`application.icons.all`	Every reachable icon, in one list.

For a store row, a catalog card, or a launcher tile:

const icon = app.application.icons.primary;
if (icon) {
  img.src = icon.src;
  img.width = icon.width ?? 64;
  img.height = icon.height ?? 64;
}

If primary is null, the site did not ship a usable icon. Leave a blank or a generic placeholder in your UI — PWARegistry will not invent artwork.

Icons are not proxied. The src is the origin URL. Hotlink with referrerpolicy="no-referrer". If a file later 404s, the next health pass will notice.

capabilities.maskableIcon is true when at least one maskable icon was observed.
