  "prompt": "A realistic two-panel vertical iPhone portrait diptych of two people, maintaining exact facial likeness to the provided reference photos. Both panels share identical camera angle, spacing, focal length, and composition as if taken consecutively in the same seat at a lush café with dense bamboo, tropical foliage, and a warm wooden table in soft, diffused daylight.\n\nUpper panel — [Subject 1]: seated, holding a reflective silver smartphone with a jeweled ring grip; deep-red manicured nails; wearing a [blue-and-white gingham off-shoulder dress with seersucker texture] and a [white lace bandana]; holding an iced matcha glass with visible condensation beads, subtle fingerprint smudges, and layered green-and-cream gradients.\n\nLower panel — [Subject 2]: seated, mirroring the candid pose, holding a matte metallic phone with faint scuffs; wearing a [cream linen shirt], [brown trucker cap], and beaded accessories; raising a tall glass of iced latte showing layered coffee and milk, melting ice cubes, and frosted condensation.\n\nDetails & Camera: authentic iPhone portrait mode aesthetics with shallow depth of field, natural bokeh, and crisp focus on faces and glasses. Realistic micro-textures including water rings on wood, leaf imperfections, fabric slubs, natural skin pores, and soft specular highlights on glass and metal.",
