/* Plain 2D opacity crossfade instead of a 3D rotateY flip.
   Safari has a well-known bug where backdrop-filter on an ancestor
   (our .digit-slot cards use one for the glass panel look) breaks
   backface-visibility on nested 3D-transformed children -- the
   hidden face bleeds through intermittently. This sidesteps it
   entirely by never using 3D transforms here. */
