/* Wedding Souls.in — home gallery (gallery.js, scripts/edits/gallery_section.py).

   Default (phones, tablets, reduced motion, no script): a strip that scrolls
   sideways inside itself and snaps to each photo. On wide screens gallery.js adds
   .is-pinned to the section: the stage holds the screen and the track slides
   sideways as the page scrolls. Only transform, opacity and clip-path animate. */
