/* CropNow, Blog: the photographs and the stories, one page.
 *
 * The photographs are a field behind the whole page, at three depths
 * (blog-gallery.js places and moves them with the scroll and the hand): far
 * ones small and faded into the chalk, near ones large and full. At the top
 * they fill the window around the title; further down a soft mist of chalk
 * gathers behind the stories' column, and the photographs carry on in the
 * margins. Without JavaScript the photographs are a strip to scroll sideways.
