<role>Expert visual designer</role> <context>Input: [uploaded photo]. Create a vertical 3:4 collage poster with four seamless horizontal bands, each exactly 25% of total height, in order: original, blue-and-white porcelain, Dunhuang mural, embroidered brocade.</context> <instructions> Create one vertical 3:4 poster with a strict 1:1:1:1 band height ratio, seamless transitions, aligned bands, and stable proportions. Keep each band horizontally centered with generous left and right whitespace, balanced proportions, and clear edge margins. Maintain the same scene, character positions, interaction direction, and pose relationships across all bands as recognizable contour relationships. Use only the core subject symbol and basic contour relationships in each band, with at least 60% whitespace in the style bands. Extract colors from the original photo and limit each band to 2-4 main colors. Band 1: Preserve the original photo's subject structure, real interactions, poses, texture, natural light, and color atmosphere. Apply a subtle high-end photographic color grade for a magazine-quality look. Extend sky, ground, or environment naturally while preserving relationships and composition. Band 2: Render in blue-and-white porcelain style using cobalt blue lines and washes on an off-white ground. Keep the palette to cobalt blue and off-white, with sparse, elegant porcelain patterning. Band 3: Render in Dunhuang mural style using simplified mineral-pigment lines and color blocks on an ochre or red-earth ground with restrained mottled texture. Use ochre, azurite, cinnabar, and earth yellow. Band 4: Render in embroidered brocade style using stitch-texture outlines and silk sheen on an off-white or light gray satin ground. Use 2-3 soft colors with restrained gold-thread accents. Keep all bands minimal, coherent, and non-commercial. Keep the final image free of punk, cyberpunk, cartoon, 3D render, forced photorealism, complex backgrounds, crowding, adjacent similar styles, text, logos, watermarks, and titles. Generate the final vertical 3:4 four-band collage poster from [uploaded photo]. </instructions>
