+/**
+ * `AppStoreKit` `Storage` implementation for the "web" client
+ *
+ * Note: The `AppStoreKit` `Storage` interface is declared as a global, which has the (presumably
+ * accidental) side-effect of implicitly being merged with the DOM library's own `Storage` interface
+ * (like `localStorage`), since interfaces declared in the same scope are merged together by TypeScript.
+ * There's no way to tell TypeScript that we only care about the `AppStoreKit` part of it, so
+ * satifying TypeScript here means that we need to implement both interfaces.
