/* Rediseño minimalista: portada con la Luna enorme, vista general con solo los puntos y un panel
 * de configuración. Se carga después de styles.css y reemplaza su disposición: los paneles fijos de la
 * versión anterior (#left, #controls, #sidebar) ya no existen.
 *
 * Idea de diseño: un tomador de decisiones no necesita ver todo a la vez. Lo único siempre visible es la
 * fecha; la ficha de un sitio aparece al elegirlo, y "Comparar" solo cuando hay 2 o más elegidos.
