   No fixed-height box and no background behind the main image - a fixed
   box forces either cropping (object-fit:cover) or visible letterboxing
   (object-fit:contain inside a box taller/wider than the photo), and both
   read as "added margin" around images that don't share the same aspect
   ratio. Letting the image render at its own natural proportions (width
   100%, height auto) preserves exactly the composition and whitespace the
   original photo already has, nothing more, nothing less. */
