/* --- photography --------------------------------------------
   A series is a cover, a few lines, then groups of pictures in justified
   rows. build.py cuts each group into rows and gives every picture a flex
   share equal to its aspect ratio, so the pictures in a row come out the
   same height; a short row narrows to --share instead of towering. On a
   phone each picture takes the full width. Travel styles apply underneath
   (the article is also .post--travel).
