Your question has nothing to do with the OP’s question, as his “picture” is the "background-image ( in Picture-Element.Card )… And your’s a picture-entity-card( which havent got the “style-option” )
Anyway …
You might be able to do what you want, with Card-Mod ( CSS ) . search for " card-mod , pictue-entity-card "
PS: however, You do know what happens when you ( rotate a picture/stream ) 90 degree ? … it will show/flip the picture, so you have to “bend” your head 90 degree also, Even if you flip your phone to horizontal view
However, I tried to modify it, because I don’t remember using this transform (too long ago
It does not change something, if I use e.g. transform: rotate(-0.75turn)
