   NORMALIZACIÓN DE TARJETAS
   Las tarjetas que son <button> llevan <span> dentro, porque un botón

   <span> es inline por defecto, así que sin esto los marcos colapsan a
   cero de alto y los elementos absolutos se van a la esquina. Era el
   motivo de que el último video saliera como un rectángulo negro con el
   play cortado en el borde izquierdo.
   ===================================================================== */
