// This permission context is responsible for getting, deciding on and updating
// the Periodic Background Sync permission for a particular website. This
// permission guards the use of the Periodic Background Sync API. It's not being
// persisted because it's dynamic and relies on either the presence of a PWA for
// the origin, and the Periodic and one-shot Background Sync content settings.
// The user is never prompted for this permission. They can disable the feature
// by disabling the (one-shot) Background Sync permission from content settings
// UI. The periodic Background Sync content setting can be disabled via Finch,
// and will prevent usage of the API.
// The permission decision is made as follows:
// If the feature is disabled, deny.
// If we're on Android, and there's a TWA installed for the origin, grant
// permission.
// For other platforms, if there's no PWA installed for the origin, deny.
// If there is a PWA installed, grant/deny permission based on whether the
// one-shot Background Sync content setting is set to allow/block.
