A loader / background ambient texture reproducing a risograph duplication run: three sequential drum passes reading the same shared stencil field, each a rotation sweeping the sheet top-to-bottom, cumulatively drifting a few pixels out of register against the pass before it, with per-rotation drum-pressure banding baked into each row as it prints.
