/**
 * Patch @rmdes/indiekit-endpoint-webmention-sender webmention.js to:
 *
 * Scope link extraction to the post content area only (.e-content inside
 * .h-entry, or <article>, or <main>) when processing a full page.
 * Without this, links from the sidebar, navigation, and footer are included
 * because the live-fetch patch fetches the full rendered page HTML.
 *
 * Falls back to the whole document when no content container is found
 * (e.g. when processing a stored post body fragment rather than a full page).
