/* Floorwalker marketing site.
   Layout: a shop-floor ticket board. Condensed signage headlines, receipt-mono times and
   prices, and the app's own screens as the objects on show. Palette and radii come from the
   Floorwalker app (warm grey ground, one bottle-green accent, 14-16px card radii). */
