Premium brand takeaway packaging design proposal board

Generate a horizontal 4:3 high-definition realistic brand packaging design proposal board, with the theme of [Product Category] takeaway 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, small cards, wrapping paper, napkins, real product accents]

The image should look like a high-end brand packaging proposal board, rather than a single product photography image. It needs to simultaneously display:
Graphic design drafts, packaging structural diagrams, real physical mockups, small application scenario images, material color swatches, logo/icon systems, paper textures, local functional details, and handwritten marks.

Horizontal 4:3 composition, top left is the main title and brand information, left side is the graphic design draft and structural unfolding diagram, top right is a large-area real packaging mockup main visual, the middle part is small application scenario images, bottom right is DETAILS & MATERIALS, bottom is CONSTRUCTION & FUNCTION local details.

The overall feeling should have a sense of design, proposal, handmade touch, and a real commercial implementation feel. Add hand-drawn arrows, handwritten notes, circles, underlines, paper collage feel, soft shadows, and natural white space. Physical mockups must be three-dimensionally realistic, with paper thickness, box creases, transparent materials, printing texture, and natural light and shadow.

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