/* #877: product page on phones and tablets (the single-column layout, 1040px and under).
   1. The buy box moves up to sit right under the gallery; the review spotlight follows it.
   2. The gallery thumbnails become one swipeable row.
   3. A buy bar stays pinned to the bottom of the screen while the real Add to cart is off screen.
   Selectors start at .product-page so they win over the bundle, which loads after this file.
