Create a vertical poster showcasing the Gong'an Guokui product in a minimalist geometric style. Use a clean, bright white or warm white studio background with a high-key lighting setup to convey a modern, premium commercial brand vibe. The composition should blend brand visual proposal, artistic still life photography, and 3D product display concepts. Include the main product, its packaging, and related elements such as ingredients, slices, components, or material details to form a clear visual story. Incorporate simple, well-designed geometric props like cylinders, cubes, rings, spheres, platforms, stacked blocks, acrylic stands, or toy-like structures to support and frame the product, creating an orderly, rhythmic, and layered artistic arrangement. The color palette should naturally revolve around the product’s core colors, complemented by neutral tones like white, cream, and light gray, with subtle accent colors as needed for a unified, restrained, fresh look. Materials should be rendered with delicate realism, showing textures like transparent plastic, acrylic, frosted surfaces, paper labels, glass, metal, smooth plastic, fruit pulp, or food textures with slight reflections and soft shadows but no heavy or messy effects. Ensure ample negative space, clear focus, balanced and tidy visuals with a light, gentle, modern, refined, approachable, and slightly playful but not childish brand character. The final image should feel like a high-aesthetic brand key visual poster, ideal for e-commerce main visuals, social media promotion, and product display.
