Generate a landscape 4:3 high-definition realistic brand packaging design presentation board, themed around a [product category] takeaway packaging system. Brand name: [Brand name] Slogan: [Brand slogan] System title: [TAKEAWAY PACKAGING SYSTEM] Style: [Style keywords] Main color palette: [Main color palette] Product materials: [Paper bag, cup, box, sticker, small card, wrapping paper, napkin, real product embellishments] The image should look like a high-end brand packaging presentation board, rather than a single product photograph. It needs to showcase: Graphic design drafts, packaging structural diagrams, realistic physical mockups, application scene thumbnails, material color swatches, logo/icon system, paper textures, functional close-up details, and handwritten annotations. Landscape 4:3 composition: top-left features the main title and brand information; left side displays graphic design drafts and structural unfolded diagrams; top-right features a large-scale main visual of realistic packaging mockups; center contains application scene thumbnails; bottom-right shows DETAILS & MATERIALS; bottom section shows CONSTRUCTION & FUNCTION close-up details. The overall aesthetic should convey design sensibility, a presentation feel, a handcrafted touch, and a sense of realistic commercial viability. Include hand-drawn arrows, handwritten notes, circles, underlines, paper collage effects, soft shadows, and natural negative space. Physical mockups must be three-dimensional and realistic, featuring paper thickness, box creases, transparent materials, print textures, and natural light and shadow. Avoid generic advertising images, white-background e-commerce photos, stiff collages, thick-lined grids, garbled text, low resolution, packaging distortion, flat imagery, and a cheap look.
