/*
 * The site header and footer, the same on every page: the homepage, the
 * articles and their index, the area pages, the privacy policy and the 404
 * page. scripts/build_chrome.py writes the markup into each page and links
 * this file with ?v= (a hash of it), so edit it here and run `make check`.
 * The header comes first, the footer after it.
 *
 * Self-contained on purpose. It carries its own copy of the palette (the same
 * values as the :root tokens in index.html and article.css), because the
 * privacy and 404 pages define no tokens, and so a page's own styles cannot
 * change how the header or footer looks.
 *
 * Header widths:
 *   1200px up     full bar: wordmark and tagline, six links, phone and WhatsApp buttons
 *                 (the container stops growing at 1200px, so this is its widest).
 *                 Reviews, the least needed of the seven links, is never in the
 *                 bar: with Midwifery added the row would not fit. It is always
 *                 in the collapsed menu, and the reviews are on the homepage.
 *   under 1200px  snug: the gaps close up a little
 *   1140px down   collapsed: wordmark, phone and WhatsApp buttons, menu button; the
 *                 menu holds all seven links, then WhatsApp, phone and email
 *   640px down    the WhatsApp button loses its label and goes round
 *   560px down    the tagline goes, the gutter narrows to the homepage's 22px
 *   360px down    a little smaller again, so a 320px phone never scrolls sideways
 * Every step is a max-width, and each one is written as N.98px (so "1140px
 * down" is max-width: 1140.98px). Browser zoom and high-density screens can
 * give a viewport like 1140.5px wide, and a plain 1140px/1141px pair would
 * leave that width matching neither the full bar's rules nor the collapsed
 * ones, so the full bar would spill off the side.
 * header.js needs none of these numbers: it asks whether the menu button shows.
