/* v11 · "Open house"
   One white architectural model on paper. The page scrolls and the camera walks through it.
   Colour comes only from the work on the walls, and from one red sun at the end of the sightline.
   One typeface (Archivo): width does the hierarchy. Giant and condensed for the few big things, plain for the rest. */
