Cross-Legged Floor Pose Sheet

Create a 4:5 vertical original pose reference image titled "Cross-Legged Floor Pose Sheet". Show the same adult original character in three cross-legged floor pose variations on a pale gray background: upright cross-legged sitting, hugging knees, and leaning forward while seated. Keep the same outfit in all poses: loose white shirt, deep blue trousers, pale socks. Arrange the three figures side by side without overlap, like a clean pose sheet with no text labels. Emphasize knee direction, pelvic tilt, arm support, relaxed shoulders and neck, and natural anatomy. No real brands, watermarks, garbled text, or unrelated logos.

生成一张 4:5 竖版原创动作参考图，主题为「盘腿坐姿动作参考」。同一位成年原创角色在浅灰背景中做三种盘腿坐姿变体：端正盘腿、抱膝盘腿、身体前倾盘腿。每个姿态保持同样服装：宽松白衬衫、深蓝长裤、浅色袜子。构图像干净的姿势表，三个人物并排但不重叠，不要文字标签。重点展示膝盖方向、骨盆倾斜、手臂支撑和肩颈放松。不要出现真实品牌、水印、乱码或无关标识。
