The burrow's cost is still waiting for a measured table.

How it was drawn

Generated with codex exec -m gpt-6-luna (image generation), then passed through the plate pipeline: art-direction.md: flatten on white, grayscale, luminance to alpha (rgb = L, alpha = 255 - L) with Sharp.

A single earthen burrow cell drawn as a cutaway: a small rounded chamber in the soil, roots reaching around it, holding one small humming generator machine with a hanging lantern and a few cables running up into the roots. Hand-drawn field-journal sketch in loose graphite pencil line work, monochrome grey, confident gestural outlines, quick cross-hatching and scribbled hatch shading only, no smooth airbrushed or painted shading, unfinished edges fading out into white. 19th-century naturalist's working notebook, documentary object study, no color. One single subject, centered, tall portrait frame (about 3:4) with generous white margin. Opaque pure flat white background (not transparent), no paper texture, border, frame, vignette, labels, lettering, or text.
