คอลลาจภาพถ่ายท้าทายกล่องคริสต์มาส 2x2

A detailed prompt for Nano Banana Pro to create a 2x2 photo collage with a Christmas theme, featuring a young woman posing inside cardboard boxes. The critical feature is the seamless interaction between the top-right and bottom-right panels, where red wine poured in the upper panel flows down into a glass held in the lower panel, strictly maintaining the subject's facial identity.
