/* Стальные Войны — the front of the house.
 *
 * One screen decides this page: a machine in a dust bowl, a title low on the left, and one button.
 * Everything below it exists to be scrolled past by somebody who has already pressed that button.
 *
 * Colour is restrained on purpose. The photograph is the only place saturated colour is allowed to
 * live; the chrome is warm near-black and sand, and ember belongs to the single action and to
 * nothing else — the moment a second thing is ember, the button stops being the loudest object.
 *
 * Two faces. Tektur for display: angular, built rather than drawn, and with a Cyrillic that holds
 * at 60px. Golos Text for everything read. No third face for "technical" flavour — monospace worn
 * as a costume is a costume, and numbers get tabular figures from the body face instead.
 *
 * One theme, and it is dark, because the game is dust at low sun and a light page beside it looks
 * like a different product. Everything is painted explicitly rather than inherited.
