[Product and Copy]

• Main Copy: {argument name="main copy" default="Ultra-lightweight, High Volume! Latest Portable Speaker"}
• Onomatopoeia: {argument name="onomatopoeia" default="BOOM!!"}
• Text inside Speech Bubble: {argument name="speech bubble" default="Awesome!"}

[Quality, Production, Composition]

• Style: Vintage pop art illustration characterized by dot (halftone) textures and strong black outlines, like the style of Roy Lichtenstein or American comics.
• Subject: A product drawn as if it were jumping out vigorously in the center. Radial lines (focus lines) spread from behind the product, enhancing the sense of dynamism.
• Typography and Speech Bubbles (for GPT-image / Nano Banana Pro): The onomatopoeia {argument name="onomatopoeia" default="BOOM!!"} is drawn in large, powerful, 3D colorful comic-style letters, and the text {argument name="speech bubble" default="Awesome!"} is placed inside a classic speech balloon. A banner for {argument name="main copy" default="Ultra-lightweight, High Volume! Latest Portable Speaker"} is designed at the top of the screen.
• Color/Tone: Vivid and high-contrast pop art colors such as yellow, red, blue, and black.

[Strict Layout and Output Constraints (Required)]

• Output the finished design itself, filling the entire screen. Backgrounds and scene descriptions (walls, spaces, shadows, etc.) within the design may follow the instructions in the main text.

• Prohibitions: Photos of the finished poster in a frame, photos pinned to a wall, mockup photos placed on a desk or paper, perspective distortion of paper edges, or drop shadows.

• Output the finished flat 2D design itself, filling the entire canvas. Scene elements inside the design (walls, rooms, shadows) described above are allowed. Absolutely NO photo-of-a-poster mockups: no picture frames, no poster-on-wall or poster-on-desk shots, no perspective warp or drop shadow around the artwork's edges.

• Aspect Ratio: "--ar 1:1" or "--ar 4:3"
