   Concept: "the firing". Raw material goes into a dark chamber and comes out
   holding its shape. Surfaces are char and graphite; the accent is the heat
   inside — ember for marks, flame for the light that falls on things.
   Imagery is generated in the same heat ramp, so unrelated compositions read
   as one owned image system. See DESIGN.md.
