 * The same drawing as the apps: one steel accent across its ramp and no second
 * hue, square corners, hairline rules, Barlow Condensed over Barlow. Shared by
 * every page so the site and the games cannot drift apart.
 *
 * Kept as one small stylesheet rather than inlined twice - a policy page and a
 * landing page that disagree about their own colours is exactly how a site
 * starts looking abandoned. */
