怎么填变量：[环保小机器人] 是角色主题，可以换成"海洋清洁小机器人""快递小机器人""咖啡师小机器人"，同时把头顶的嫩芽、胸口的徽记换成对应的元素（水滴、包裹、咖啡杯）；[柔和的象牙奶油色] 和 [叶绿色] 是主色和点缀色，海洋主题可改成"珍珠白 + 湖蓝"；[纯白背景] 需要抠图时保持不变，想直接当头像可以写"浅绿色纯色背景"。

示例图是白底正中的像素小机器人：奶油色的大圆头，黑色面罩里两只绿色大眼睛各有一颗白色爱心高光，下面一道小小的白色微笑；头顶两片绿叶，额头和胸口的绿色面板上都有白色嫩芽图标；两侧是绿色圆耳舱，画面左侧的手臂抬起打招呼，另一只垂在身侧，脚上是奶油色配绿色的短靴。

常见问题：

• 像素边缘发虚：加"硬边像素、不要抗锯齿和模糊"，需要低分辨率素材时再自行缩小到 64×64。
• 想要动作序列：追加"同一角色的站立、挥手、行走、跳跃 4 帧，横向排成一行"。

适合：环保 / 植物类项目的吉祥物、社群头像、贴纸、独立游戏角色草案；正式做游戏素材还需要按引擎要求重新对齐像素网格。

Create a centered full-body pixel art mascot robot on a clean {argument name="background" default="plain white background"}. The character is a cute chibi eco robot with a cream-colored rounded helmet-like head and body, dark black face screen, and green plant-themed accents in a retro 16-bit/32-bit pixel style with visible square pixels, crisp black outline, and soft shaded highlights. The robot has exactly 2 large glossy green eyes with white heart-shaped highlights, a tiny white smiling mouth, exactly 2 round green side ear pods, exactly 2 green sprout leaves growing from the top antenna, and a small green forehead panel decorated with a white sprout icon plus 2 white dots. The body is compact and rounded with a square green chest panel showing a white sprout emblem, exactly 2 arms with green joints, the left arm raised in a friendly wave with a small green segmented hand, the right arm hanging down with a chunkier cream forearm and green hand, exactly 2 short legs, and exactly 2 cream-and-green boots. Use a warm palette of {argument name="main body color" default="soft ivory cream"}, {argument name="accent color" default="leaf green"}, deep black for the face visor, and subtle yellow-green highlights. Make the mascot adorable, symmetrical, front-facing, isolated, no text, no watermark, no extra props, high-resolution pixel art with a slight grid-like pixel texture.
