/* Kit común de la Zona Niños · sistema «Pixel suave 2» (2026-11-07), el mismo de toda la web (/cq.css) en versión
   algo más grande para peques: Bricolage Grotesque en títulos, DM Sans en texto, tarjetas blancas con borde de tinta
   y sombra «de bloque», iconos y cielo en pixel art detallado (los pinta ui.js). Uso (sin cambios de API):
     <link rel="stylesheet" href="/ninos/ui.css?v=6"> + <script src="/ninos/ui.js?v=7" defer></script>
     <div class="k-sky"></div>   (fondo crema con cielo, sol, nubes y colinas pixel; lo rellena ui.js)
     <header class="k-bar"><a class="k-round" href="/ninos/" data-k-icon="home" aria-label="Zona Niños"></a>
       <h1>TÍTULO</h1><button class="k-round k-mute" aria-label="Silencio"></button></header>
   Clases: .k-card (tarjeta blanca), .k-btn (botón; .alt .pink .blue), .k-title, .k-note, .k-me (avatar en la barra).
   Las variables antiguas (--ink, --pink, --round, --pixel…) se redefinen con más prioridad que los :root de cada juego,
   así todos los juegos heredan colores y letra nuevos sin tocar su lógica. */
