 * Photo gallery: Swiper main slider + thumbnail rail + full-screen lightbox.

 * in single-attraction.css); single-post-day-trip.php loads this file to reuse
 * it under the featured image. Class names stay .attraction-* on purpose so the
 * markup and gallery.js are interchangeable between the two templates.
