   Identity: "signal on deep space". A deep blue-black canvas, warm signal light
   (the same orange the network uses for activations). Type: Schibsted Grotesk,
   a sturdy grotesk; emphasis by weight and colour only. Layered rounded surfaces (bento), hairline borders, light only
   where something is actually happening.
