   Orion Stil — design system v2 ("golden hour on anthracite")

   Dark, cinematic ground: the colour of the product (RAL 7016 anthracite)
   under the light it is photographed in (Dalmatian golden hour). Limestone
   bands break the rhythm the way a stone wall breaks a fence line.

   Type: Archivo on its width axis — expanded for display, like lettering
   cut into a steel plate — with Instrument Serif italics for the one word
   that carries the feeling, Source Sans 3 for reading, IBM Plex Mono for
   dimensions and labels.
