/*
 * Privacy, Terms and Support (/<lang>/privacy, /terms, /support).
 *
 * The same look as the Secret Santa pages (santa.css) and the app's
 * KeepTheme: paper-notebook cream, forest ink, a New York serif for headings
 * and the hand-drawn art on a peach-to-sage panel. On a phone it's one column
 * with tabs; from 900px wide it becomes the desktop layout with a top bar.
 * Built with logical properties, so Arabic mirrors itself. The header,
 * footer and language sheet are shared with other pages: site.css.
