/* ============================================================
   The Global Leadership Summit — country sites  ·  v2
   Light, warm, photographic. One brand palette for all six
   countries; the flag and the content carry the country.

   Why one palette: six flag-coloured sites read as six unrelated
   projects. GLS is a single global brand arriving locally, so the
   brand stays constant and the country shows through the flag,
   the cities, the venues and the photographs.
