/* PatchWard — overview site.

   Direction: light, quiet, roomy. The only things allowed to be dramatic are
   the product's own screens — they are dark, so on a near-white page they read
   as objects sitting on a table. All the 3D is applied to those screens and to
   the pieces of interface lifted out of them (the navigation column, a wave
   card): perspective, layered depth and pointer parallax, no abstract shapes.

   Palette comes from the logo: navy ink, steel blue, paper white. Status colour
   (green) appears only where it means something, borrowed from the app.
   No external assets. */
