Use the imagegen skill in its default built-in mode (the built-in image_gen tool). Generate exactly one image and nothing else.

Use case: product-mockup
Asset type: brand book photograph (realistic print mockup) for the Reload brand manual
Input images: Image 1 is the exact poster artwork (portrait 4:5): white dots on a Reload-blue field, a dot screen where two point sources create an interference pattern of rings. Reproduce its layout 1:1 as the print.
Primary request: a photograph of a risograph poster of Image 1 hanging on a white studio wall. It is printed in a single blue riso ink close to Reload blue (#0056FF) on white uncoated paper: the blue field is a riso ink flood with visible grain, slight unevenness and tiny white specks, and every white dot is bare paper. The print is slightly off-register on the sheet: shifted a couple of millimetres and a fraction of a degree, so the white margins are uneven.
Scene/backdrop: white-painted brick wall of a small design studio; the poster hangs from two small black bulldog clips on nails; daylight.
Style/medium: photorealistic editorial photography, 50mm lens, f/4, real paper texture, the riso grain visible up close.
Composition/framing: frontal with a slight angle, the poster fills about 70% of the frame height with a bit of wall around it; portrait 4:5.
Lighting/mood: soft daylight from a window at the side, a gentle shadow under the paper's slightly wavy edges; quiet studio mood.
Color palette: white paper, white wall, black clips; the only saturated color is the blue ink.
Materials/textures: 120 gsm uncoated paper with a slight wave, riso ink grain, faint roller marks in the flood.
Constraints: reproduce the dot pattern of Image 1 faithfully (same positions of the two sources and their rings); no text, credits, titles or logos added anywhere.
Avoid: glossy print, glow, gradients, other ink colors, colored props, plants, CGI look.

After the image is generated, copy the final PNG to ./batchA/riso-poster.png (relative to the current working directory) and print the absolute path. Do not edit any other files.
