/* THE DRAWING — the second signature interaction.

   One composition, never seven popups: an editorial column, the plan itself,
   and a preview that changes inside the same frame. Choosing a room dims the
   rest of the house, draws a perimeter around the room you chose and runs a
   hairline from that room across to the photograph of it.

   The plan image carries burnt-in labels. They belong to the drawing; the
   site's room names, descriptions and accessible labels come from
   assets/js/property.js and never from the picture. */
