Photorealistic interior photograph, vertical 9:16. Place EXACTLY the sofa from the reference image (teal/petrol velvet corner sofa, two adjustable headrests, wide box armrest on the left, open chaise longue on the right, two loose teal cushions, thin black metal frame legs) — keep its shape, proportions, color and fabric identical. Setting: a classic German Altbau living room — high ceiling with ornate stucco moulding, wall panelling in warm off-white, herringbone oak parquet, white marble fireplace with a gilded mirror, tall double windows with heavy linen curtains, vintage Persian rug, brass chandelier, antique side table. Straight-on, eye-level camera at 3/4 angle matching the reference, sofa in the lower-middle of the frame, calm area above for text. No people, no text, no logos.
