/*
 * The header, footer and language sheet every public page shares
 * (Tools/site/chrome.js): the legal pages and the Secret Santa landing pages.
 *
 * Loaded after the page's own stylesheet (legal.css or santa.css), which
 * defines the colors and fonts used here. On a phone the header is the
 * wordmark and the language button; from 900px it adds the navigation and
 * Get Keepwell. Logical properties, so Arabic mirrors itself.
