/* =========================================================================
   Guess the City — landmark pages
   -------------------------------------------------------------------------
   An atlas, not a travel blog. The reference these pages compete against is
   the listicle, so the answer is not more colour: it is the authority of a
   well-set gazetteer. Warm paper, deep ink, and one accent — the verdigris
   that copper turns after a century outdoors.

   The layout is a three-track grid so photographs can break out past the
   text measure while prose stays at a readable width. Nothing else breaks
   the grid, which is what makes the plates land.
