   Ponsegle landing.

   The visual language comes from the mark: brushed chrome, a cool mint cast,
   light arriving from above. Surfaces are built from that one idea — a bright
   top edge, a dark bottom edge, and a soft shadow underneath — so depth reads
   as material rather than decoration. Motion is slow and singular; nothing
   moves unless it is telling you something.
