现代孔版印刷风格咖啡馆海报

Flat modern risograph-style poster illustration of {argument name="subject" default="HUMAN"}, wearing {argument name="clothing" default="minimal clothing"}, sitting front-facing behind a simple café table with {argument name="companion" default="ANIMAL"} in {argument name="setting" default="SCENERY"}. Use [COLORS] as flat solid color blocks on warm cream paper, with simple black hand-drawn outlines, naive proportions, minimal facial features, tiny dash textures, visible speckled print grain, slightly imperfect registration, clean graphic shapes, playful folk-poster composition, and a calm centered layout. The background is {argument name="background" default="BACKGROUND"}, simplified into flat wall shapes, one framed poster, one window shape, one potted plant, and a few rounded hanging lanterns. Keep the table objects simple: one bottle, one glass, one plate of food, and two tiny charms. Rounded cream border, retro Japanese picture-book poster feel, aspect ratio 4:5.
