Expand the vertical photo into a wide landscape 16:9 aspect ratio (outpainting). Seamlessly extend the background environment to the left and right sides while keeping the three central people, their poses, facial expressions, clothes, and lighting perfectly intact: the smiling young boy with a black backpack hugging his mother in a light beige hijab and dress, and the friendly Asian teacher/staff woman in purple scrubs standing beside them. The environment is a bright, cozy modern nursery, kindergarten, or pediatric clinic lobby with warm natural sunlight, wooden slatted paneling, indoor potted green plants, shelves with colorful children's toys and books, large glass windows, and a warm, welcoming atmosphere. Maintain the exact realistic photography style, soft warm colors, and high detail.
