/* ============ TEMA DE LA LANDING ============
   La landing se diseñó solo en oscuro, con los colores escritos directo, y por eso
   index.aspx escondía el botón de tema. Ahora todos los colores propios pasan por estas
   variables: los oscuros son los de antes (algunas transparencias casi iguales quedaron
   en una sola) y los claros cumplen contraste de texto >= 4.5:1 y de acentos >= 3:1. */
