Unzipping the Stormy Sky

Generate exactly one original anime illustration, portrait 3:4, text only with no reference pixels. A small adult maintenance worker on a red rooftop leans backward, pulling a long rope attached to an enormous zipper slider embedded vertically in the stormy sky. Above the moving slider, two heavy purple cloud edges separate along visible silver zipper teeth, revealing a narrow wedge of luminous peach dawn. Below it the cloud seam remains closed and rain continues. Show the taut rope, the worker's grounded boots and the slider's exact position so the physical cause is readable. Dramatic upward viewpoint, spare architectural foreground, expressive hand-painted clouds, economical sharp linework. No words, symbols, logos, familiar characters or watermark.
