Living Room Sofa Blanket Fort Triangle

Full prompt

Geometric composition in a cozy living room, where a playful blanket fort built from sofa cushions and duvets forms a natural triangular entrance. Peeking out from inside the dark fort, a child shines a bright flashlight along a dramatic diagonal line directly at the father crouching in the lower right corner, who playfully feigns defeat. The stable triangular geometry of the fort frames the dynamic beam of light and the warm, heartwarming family interaction, with deep shadows and cinematic contrast, aspect ratio 9:16.
