   DARKROOM — premium theme for Selfish
   Photographs first. The home page is a contact sheet of square
   frames on near-black, and each post prints its photos wider
   than its words. Neutral greys, so nothing tints a picture.
   Dark for every reader; Always light turns the lights on.
   Uses the CardGridThemeRenderer (.post-card grid).
