/* Mobile: the sticky offset's `top:76px` isn't reset by `position:static`
   above alone — the image wrap's own inline `style="position:relative"`
   (needed so its absolutely-positioned badges/dots have a containing
   block) keeps `top:76px` active as a relative offset, visually shifting
   the image down without reserving that space, so the next sibling
   (product info) overlapped it by ~44px. `top:0` neutralizes the shift
   while still letting the inline position:relative anchor the badges. */
