局部编辑：旋转笔记本电脑并添加 Logo

Using the provided reference image, make a localized edit only: rotate the laptop at the lower left so the back of the screen faces the viewer instead of the keyboard, and add a cute robot mascot logo centered on the back cover. Keep the rest of the illustration unchanged, including the characters, room decor, lighting, watercolor anime style, desk items, and overall composition.

使用提供的参考图像进行局部编辑：将左下角的笔记本电脑旋转，使其屏幕背面朝向观众而非键盘，并在背面中心添加一个可爱的机器人吉祥物 Logo。保持插图的其余部分不变，包括人物、房间装饰、光影、水彩动漫风格、桌面物品以及整体构图。
