The horizon band

A page header made of seismic: a window of one section as texture, a geometry the eye reads and nothing else. Each reflector takes the next ink in turn from the fjord and cobalt steps, so the layers alternate in colour; seismic does not do that, a header may. Where a page has interpreted surfaces to show, they can be drawn as lines with the page's own in the highlight. A replacement for the drawn motif that opens a SubScout story, in the same tokens.
