/* ============================================================
   NOBLE HOMES / ETN HOMES — SITE STYLES
   Design concept: "Contour" — the winding shoreline of a Finger
   Lake, and the contour lines of a surveyor's map, rendered as a
   quiet thread running through the whole site. Palette pulls from
   lake water, fieldstone, and aged copper — the actual materials
   of upstate New York estate work.
