/* Strax
 *
 * A wall of photographs, so the photographs are the design and everything else
 * gets out of their way. The old version put each frame in a bordered card with
 * a caption bar under it, which meant a screen of boxes with pictures in them
 * rather than a screen of pictures.
 *
 * Near-black rather than dark grey: a photograph shown against #1c1f25 has its
 * shadows lifted by the surround, and a press box wall at night is bright
 * enough already.
