/* Landmark Guyana public site.
   A survey sheet laid on the land: every page opens on a deep green band drawn
   with contour lines (our own tile, public/img/topo.svg), the map or photo sits
   on the sheet's edge, and the lists below run on pale, faintly grained paper.
   The one loud colour is the gold "Take me there" — green and gold, the flag. */
