/* MSOS — "Add as a preferred source on Google".
 * (1) A small text link in the footer (.legal-links) on every page.
 * (2) An interactive pill button on the homepage, News hub and Blog hub
 *     (Google's official button via publisher.js; renders any element with
 *     the google-add-preferred-source-btn attribute).
 * Self-contained, no dependencies. Domain-level deeplink works everywhere;
 * the pill needs Google's library, loaded only on the hub pages.  */
