/* Dunow — a reaction game for the fold.
 *
 * Sibling to xgest.app / gososh.app / whatsfordinnertonight.org: same page
 * structure (header, brand, nav, container, footer, umbrella cross-promo), but
 * its own skin. Dunow is a game, so the site is dark, bold, and colourful — the
 * eight game tile colours as accents, medal gold for the primary action, and the
 * app's rounded-black display type. No build step, no JS required.
