   Daniel Gov — photography showcase
   A neutral dark ground and no accent colour, so the only colour on screen
   comes from the photographs. Mobile first.

   Motion: html.motion-on (set in the page head unless the visitor asked for
   reduced motion) allows the opening animation; html.motion-js (set by
   motion.js) switches on the scroll-driven layouts. Without either, the page
   is complete and still. Everything that moves uses transform or opacity.
