   PDP mini gallery - phone only (2026-10-30, Drago)

   The options column under the gallery is very tall on a phone. Once 75% of
   the main image has scrolled away, a small copy of the gallery is pinned
   under the floating header: the current image on the left (about 35% of
   the main image's height) and the six product views on the right, two
   columns of three. Built by assets/js/pdp-mini-gallery.js; the height comes
   in as --mini-h. Images are never cropped (object-fit: contain).
