   HOW TO ADD YOUR OWN PHOTOS
   Every image area on this site is a "photo block" that already
   has a designed industrial fallback. To drop in a real photo,
   set the --photo variable for that block, e.g.:

     .photo--hero { --photo: url("../img/hero.jpg"); }

   Nothing else needs to change. See README.md for the full list
   of photo slots.
