   DISPOSICIÓN · escala y distribución
   Solo afecta tamaños, espacios y la forma de repartir el espacio; no toca colores, textos ni funciones.
   Criterio: el inicio es un lanzador (se llega para ir a una herramienta), así que la portada deja de ocupar la
   pantalla entera y las herramientas se reparten en una rejilla densa de tres columnas. Dentro de los módulos
   se trabaja: tarjetas más bajas, títulos de 18 px, botones de 40 px y un ancho de lectura de 1040 px.
   Escala de espacios: 4 · 8 · 12 · 16 · 24 · 32 · 48.
