 * One sheet for the whole public site. It carries two registers, because the
 * site has two jobs:
 *
 *   - The home page is a shop window, and is allowed to be dark, gold and
 *     full-bleed, matching the game it is advertising.
 *   - The legal pages are read, sometimes by a reviewer looking for one clause,
 *     and are set as plain documents on the same ground: generous measure,
 *     ordinary link colour, no decoration competing with the text.
 *
 * The palette is the game's own: the night indigo the menu is painted on, and
 * the gold leaf of the castle's crest.
