/* HowPaano public site.
 *
 * The site carries no images, no video and no emoji, so every bit of energy has
 * to come from type, colour and space. The approach: a crisp high-contrast
 * surface, a modern grotesque at a wide weight range, and one saturated colour
 * per topic that runs through the whole page. Structure stays editorial (a
 * numbered index rather than a wall of cards) but the finish is contemporary.
 *
 * Hand-authored so the stylesheet stays one cacheable file with no build step.
