 * It is one screen: a dark field of stars, the mark, the sentence that says

 * half of it rather than living on a page of its own, because there is nothing
 * else to navigate to and a second page would be a second page of nothing.
 *
 * Written against no framework. The page it replaces loaded Bootstrap, jQuery
 * and eleven plugins to draw a logo, a paragraph and a form - about 400 KB of
 * library for a screen that needs none of it.
