//  Owns WKWebView configuration per profile: the profile's WKWebsiteDataStore
//  (persistent for normal profiles, non-persistent for private ones). All tabs
//  of a profile share cookies/storage through the same data store. Modern
//  WebKit pools and reuses content processes automatically (WKProcessPool is a
//  deprecated no-op), so no explicit pool is kept.
