/* Lunosia — the written pages
 *
 * About, privacy, terms, contact and the grammar guides: the parts of the site
 * that are documents rather than application. They borrow the palette from
 * style.css and nothing else, because the app's chrome — the nav, the fiesta
 * layer, the sticky bars — is furniture for a screen you are working in, not
 * for one you are reading.
 *
 * The shared header and footer here are the reason the site is navigable at
 * all: every written page can reach every other, and all of them can reach the
 * app. A page you can only arrive at from a sitemap is a page nobody reads.
