nanobanana — 배경 제거 + 새 배경

Take the uploaded image. Remove the background completely while preserving the subject (피사체) with crisp edges including hair/fur/transparent objects. Place the subject onto a new background: 새_배경_묘사 (clean studio gradient, beach at golden hour, modern Seoul cafe interior). Match lighting on the subject to the new background — adjust shadows, color temperature, rim light. The composite should look natural, not pasted. Output high-resolution.
