// Singleton that manages the creation & accounting for DOMStorage objects. It
// does this by holding weak references to all session storage namespaces, and
// owning the local storage namespace internally. The total cache size is
// exposed with `TotalCacheSize()`, and `ClearAreasIfNeeded()` will - if our
// total cache size is larger than `total_cache_limit` - clear away any cache
// areas in live namespaces that no longer have references from Blink objects.
//
// SessionStorage StorageNamespace objects are created with
// `CreateSessionStorageNamespace` and live as a supplement on the Page.
//
// The LocalStorage StorageNamespace object is owned internally, and
// StorageController delegates the following methods to that namespace:
// GetLocalStorageArea, AddLocalStorageInspectorStorageAgent,
// RemoveLocalStorageInspectorStorageAgent
