Tablero de propuesta de sistema de envases para llevar

Generate a horizontal 4:3 high-resolution, photorealistic brand packaging design proposal board, themed around a takeaway packaging system for 【product category】. Brand name: 【brand name】 slogan: 【brand slogan】 System title: 【TAKEAWAY PACKAGING SYSTEM】 Style: 【style keywords】 Main color: 【main color】 Product materials: 【paper bag, cups, boxes, stickers, small cards, wrapping paper, napkins, real products as accents】 The image should look like a high-end brand packaging proposal board, not a single product photo. It must simultaneously show: flat graphic designs, packaging structure diagram, real physical mockups, small application-scene images, material color swatches, logo/icon system, paper texture, local functional details, and handwritten marks. Horizontal 4:3 composition: top-left is the large title and brand info, the left side is the flat design and unfolded structure diagram, the top-right is a large-area real packaging mockup as the main visual, the center holds small application-scene images, the bottom-right is DETAILS & MATERIALS, and the bottom is CONSTRUCTION & FUNCTION local details. The whole should carry a sense of design, a proposal feel, a handcrafted touch, and real commercial viability. Add hand-drawn arrows, handwritten notes, circled marks, underlines, a paper-collage feel, soft shadows, and natural white space. The physical mockups must be three-dimensional and real, with paper thickness, box creases, transparent materials, print texture, and natural light and shadow. Avoid ordinary ad images, white-background e-commerce shots, hard collage, thick-line grids, garbled text, low resolution, deformed packaging, an overly flat composition, and a cheap look.
