/* Slideshow -- same mat, stacked images cross-fade in place.
   .landing__plate-frame is `display: grid; place-items: center` (for the

   absolutely positioned children of a grid container -- especially one
   sized with aspect-ratio -- aren't fully removed from grid auto-placement,
   so each image still claims its own row instead of overlapping. Switching
   back to a plain block box for the slideshow's own frame sidesteps it. */
