A Risszeichnung technical cutaway plate as clean modern negative draughting: ultraviolet lines plus one cyan secondary hue on near-black. A developer control rig is shown as a side elevation: review trails, tests, prompts, worktrees, diff gates, and rollback handles become mechanical levers around an empty operator chair; no face visible. The hexagonal honeycomb lattice is the frame the rig is bolted into, with a small legend swatch; one mis-struck Bureau seal near the plate-number block. Numbered German callouts: (1) review handle, (2) test brake, (3) worktree clutch, (4) the one organic part, a warm thumbprint on the control bar. Parts-list joke: 'Experte nicht enthalten, aber erforderlich.' Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
