  /* PETROLEO PLANO, y es la placa del logotipo la que manda.

     Los logotipos negativos del kit traen su fondo horneado: un rectangulo
     redondeado de #0F3D3E que ocupa el 99,7% de la pieza. Eso esta bien —es
     como la marca se firma sobre oscuro— pero obliga a la barra: si debajo hay
     otro color, la placa se ve, y el logotipo se lee como una tarjeta pegada
     encima. Aqui debajo habia un degradado del petroleo al petroleo hondo, y
     ademas translucido, asi que ni el extremo izquierdo coincidia.

     Con la barra en el mismo #0F3D3E la placa cae sobre su propio color y
     desaparece. Es lo que hizo CodeLab el 07/09; en 14_XESTIO el problema no
     se da porque su barra lateral usa la pieza TRANSPARENTE, que para el
     formato horizontal no existe en el kit.

     Y por eso se va el `backdrop-filter`: desenfocar lo que hay detras de algo
     opaco es pagar una capa de composicion en cada scroll para no ver nada. */
