Professional Brand Packaging System

Please create a high-aesthetic, high-completion "Brand Packaging System Display Image" for the brand {argument name="brand name" default="Product Category"} in the category {argument name="category" default="Brand Name"}. This is not a common e-commerce white background shot, nor a single product photo, but a brand proposal-style display showing a 'packaging family' with visual identity system logic and commercial photography texture. The image should reflect the 'unified implementation of a single brand across multiple packaging carriers,' presenting a complete packaging system for a mature consumer brand.

[Aspect Ratio Requirements] The overall composition must be a fixed 4:5 vertical poster. Horizontal compositions or scattered arrangements are prohibited. The layout should follow poster reading logic: breathing space at the top, the main visual focus of the packaging system in the center, and auxiliary packaging, labels, and products at the bottom. The weight should be concentrated and suitable for immediate release as a brand display poster.

[Core Requirements] Automatically match the most reasonable packaging combination based on the [Category] and build a unified visual system around the [Brand Name]. Choose a small but representative number of packaging forms to form a refined system. Prioritize hierarchy, brand unity, and display beauty over quantity. You can include: shopping bags, gift boxes, shipping boxes, long boxes, single item boxes, pouches, sleeves, sample bags, bottles, jars, tubes, spray bottles, pump bottles, labels, stickers, tags, cards, and the actual product itself.

[Category Adaptation] Adapt packaging forms to the [Category]: e.g., paper bags and food containers for Bakery; cups and sleeves for Coffee/Tea; jars and tubes for Beauty/Skincare; candles and cards for Fragrance/Lifestyle; drawer boxes and tags for Fashion/Collectibles. The result must feel category-appropriate and systematic.

[Quantity Control] Control the number of items; do not overcrowd. The scene should be "less is more." Suggest: 1-2 large items, 2-3 medium items, 2-4 small items/labels, and 1-3 actual products. Total visible elements should be between 6-10. Ensure enough white space and clear hierarchy.

[Visual System] All packaging must belong to the same brand system, using the [Brand Name] as the core element. Maintain consistent logo placement, font style, graphics, illustration/pattern systems, and material texture. The style can be minimalist, organic, modern, luxury, or youthful, but must be mature and high-quality.

[Color Mechanism] Avoid fixed combinations. Generate different schemes like Cream White/Caramel Brown, Mist Blue/Warm White, Olive Green/Linen Beige, Chocolate Brown/Ivory, etc. Avoid neon or cheap high-saturation colors. Maintain a sense of high-end restraint.

[Composition] Use a commercial studio setting with a 3/4 top-down or slight perspective view. Arrange in layers: large items in the background, core packaging in the mid-ground, and small items/products in the foreground. At least one product should interact with its packaging (e.g., half-out of a box). Create a balanced triangular or staggered composition.

[Visual Style] High-end commercial photography feel. Clean studio background (white, warm white, light grey). Emphasize material textures (paper folds, box structures, bottle silhouettes, print quality, embossing, matte/cotton/kraft textures). Modern and clean visual language.

[Lighting] Commercial grade lighting. Soft studio light or slight directional natural side light. Use clear but restrained shadows for depth. The light should be transparent and bright, never dark or messy.

[Final Effect] The final image should look like a mature brand's packaging proposal poster or visual landing page, emphasizing vertical poster feel, brand unity, systematic completeness, and commercial photography quality.
