// Coordinates the creation of an app banner, from detecting eligibility to
// fetching data and creating the infobar. Sites declare that they want an app
// banner using the web app manifest. One web/native app may occupy the pipeline
// at a time; navigation resets the manager and discards any work in progress.
//
// The InstallableManager fetches and validates whether a site is eligible for
// banners. The manager is first called to fetch the manifest, so we can verify
// whether the site is already installed (and on Android, divert the flow to a
// native app banner if requested). The second call completes the checking for a
// web app banner (checking manifest validity, service worker, and icon).
//
// TODO(crbug.com/41440485): Refactor this into several simpler classes,
// and remove all inheritance. Until refactor is complete, all 'virtual' methods
// that sub-classes implement must be as stateless as possible, and all state
// should be tracked in this class instead.
