/* ==========================================================================
   images.html — the image library.

   The page has one job the rest of the site does not: let someone compare the
   SHAPE of 175 pictures quickly. So every tile is drawn at roughly the same
   area with its true aspect kept, which makes a 3.2:1 header band and a
   0.44:1 vertical banner read as different objects on sight. Everything else
   here is chrome around that: a sticky filter bar, a dense size index, and a
   detail overlay that carries the paths.
