/*
    The destination gallery ("Visual Experience") and its lightbox, ported from the <style> block of the old
    includes/components/destination_gallery.php (#174).

    Two deliberate differences from the old file: a tile is a <button> (so it takes focus and the keyboard),
    and the lightbox is shown by a class (`.is-open`) and the page behind it is locked by a class on <body>
    (`.lightbox-open`) instead of by inline style attributes written by the script.
