Generate an image of a massive indoor swimming pool completely filled with thousands of floating white paper boats instead of water.

Generate an image of a massive indoor swimming pool completely filled with thousands of floating white paper boats instead of water. The pool is inside a brutalist concrete building with extremely high ceilings and huge rectangular skylights. A single lifeguard chair stands empty at the edge, and one bright yellow rubber duck sits among the paper boats as the only colorful object in the scene. Use soft overcast daylight, strong geometric composition, muted tones, clean architectural photography, subtle surrealism, realistic paper textures, and highly detailed photorealism.
