/**
 * XEP-0198 Stream Management
 *
 * The page-side {@link StanzaView} adapter.
 *
 * The page counterpart of parse.ts: where the worker builds views from raw
 * frame strings, the page builds them from the DOM Elements it already has.
 * Page-only: XMLSerializer is a DOM global, so this module must never be
 * imported by the shared-connection-worker bundle. Keeping it in its own
 * file makes that boundary structural instead of comment-enforced.
