   This is the engineering side of the studio: applications, integrations,
   migrations. The organising image is infrastructure — nodes, edges, the
   systems that carry traffic — so the site is drenched in a deep pine green
   with a single signal orange doing the work of a warning light.

   Fifth Dubyte property, fifth identity. Drenched is a strategy none of the
   others used, and the type pairing appears nowhere else in the group.
