   Tres decisiones que guían todo lo de abajo:

   1. En un teléfono, la tabla de transacciones se convierte en tarjetas. Con
      seis columnas necesitaba 807px dentro de un contenedor de 293px, así que
      el monto — el dato que uno va a buscar — quedaba fuera de pantalla.
   2. Los controles del encabezado se reparten en dos filas y el botón de
      "nuevo movimiento" pasa a ser flotante, al alcance del pulgar.
   3. Aparece una barra inferior con las cuatro pestañas de uso diario, para
      no tener que abrir el menú lateral cada vez.
