/**
 * Website frame shared by every page (home, privacy policy, 404): reading
 * size, page width, the skip link, the button, the header and the footer.
 * Colors and the font come from theme.css; each page adds its own layout on
 * top.
 *
 * Type scale for the website, used by every page stylesheet:
 * 15px small text, 18px body, 21px subheads and lead, then the fluid section
 * title (30-44px) and hero title (42-58px). The hero's popup drawing keeps the
 * extension's own smaller sizes so it matches the real popup.
