Oh, if you want it to do every page, just remove the #itemDetailPage and .detailImageContainer specifiers

Code:

.card.portraitCard img,
.card.portraitCard .cardImageContainer {
    object-fit: contain !important;
    width: 100% !important;
    height: 100% !important;
    background-size: contain !important;
    background-position: center !important;}
.card.portraitCard .cardBox:not(.visualCardBox) .cardPadder {background-color: transparent;}
