/* KHA Marine — gallery lightbox.
   Paired with kha-lightbox.js. The photo is deliberately sized with max-width /
   max-height and auto width/height rather than object-fit: contain — that way the
   <img> BOX is exactly the painted photo, which is what lets the JS measure it and
   fly it in and out of the grid tile accurately. object-fit would leave the element
   at full stage size with letterboxing inside it, and the zoom would land crooked. */
