   Marca: amarillo #F0B90B + blanco #FAFAF7 sobre fondo oscuro

   Nota: se descartó CSS muerto de una versión anterior del checkout
   que ya no existe en el HTML actual (barra de progreso de subida de
   archivo, botón "abrir broker" suelto y el file input para adjuntar
   captura) — el flujo actual pide el ID/Hash de transacción como texto,
   no una imagen, así que esas reglas no tenían ningún elemento al que
   aplicarse.
