Beverage Campaign Key Visual

[Product/Package]
- Product name/genre: {argument name="product name" default="{productName}"}
- Appeal: {argument name="tagline" default="{subText}"}

[Design Gimmick]
- Background visual element: {argument name="background element" default="{circleColor}"}

[Image quality, production, composition specification]
- Style: Pop and bright Japanese convenience store or food manufacturer campaign KV. Sizzle feeling and high visual impact.
- Subject: A can, bottle, or package of {argument name="product name" default="{productName}"} placed in the center. Surrounded by ice fragments, water droplets, splashes, or fresh raw materials (tea leaves or fruit) of the product jumping around with a sense of dynamism.
- Background: High-contrast, clear solid color or gradient background with {argument name="background element" default="{circleColor}"} placed as the main graphic element.
- Typography (for GPT-image / Nano Banana Pro): The copy "{argument name="tagline" default="{subText}"}" is placed in a thick and energetic font in a position that does not overlap with the product.
- Lighting/Color: Bright and vivid studio lighting, crystal clear reflections, energetic color composition.

[Strict layout and output constraints (Required)]
- Output the finished design itself filling the entire screen. Interior background and scene descriptions (walls, spaces, shadows, etc.) may follow the instructions in the text.
- Prohibited items: Photos of finished posters in frames, photos of posters stuck on walls, mock-up photos placed on desks 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 16:9
