Premium Packaging Design Proposal Board

Generate a horizontal 4:3 high-definition realistic brand packaging design proposal board, with the theme of [Product Category] Takeout Packaging System.

Brand Name: [Brand Name]
Slogan: [Brand Slogan]
System Title: [TAKEAWAY PACKAGING SYSTEM]
Style: [Style Keywords]
Main Color: [Main Color]
Product materials: [paper bags, cups, boxes, stickers, photo cards, wrapping paper, napkins, real product decorations]

The image should resemble a premium brand packaging proposal board, not just a single product photo. It is necessary to also show:
Graphic design drafts, packaging structure drawings, real prototypes, application scenario drawings, material color cards, logo/icon systems, paper textures, local functional details, and handwritten markings.

Landscape 4:3 composition: the top left is the large title and brand information, the left side is the graphic design draft and structural unfolded diagram, the top right shows a large, real main visual of the packaging prototype, the middle is a small image of the application scenario, the bottom right is DETAILS & MATERIALS, and the bottom is CONSTRUCTION & FUNCTION local details.

The overall design should have a sense of design, proposal sense, handmade craftsmanship, and a genuine sense of commercial implementation. Add hand-drawn arrows, handwritten notes, circles, underlines, paper collage, soft shading, and natural blank space. Physical prototypes must be three-dimensional and authentic, with paper thickness, box creases, transparent materials, printing texture, and natural lighting.

Avoid ordinary advertising images, white-background e-commerce images, hard collages, bold grid lines, garbled text, low resolution, distorted packaging, uneven images, and a cheap feel.
