/* AntHocNet — the site's front page (#545): a city-builder for networks and
   ants. Day = light, night = dark; both are selected steps, never a flip. The
   ant / packet identity colours are the validated set (adjacent CVD dE >= 8.4
   in both modes) and every glyph also differs by shape. Chrome is a modern
   game HUD: floating cards, pill controls, the map as the hero. */
