宇航员猫咪像素头像

一只圆滚滚橘色虎斑猫的32x32像素艺术头像，戴着白色宇航头盔，金色面罩微微向上掀起，玻璃上闪着细小星光反射。背景是深紫色太空网格，点缀几颗明亮的像素星星。复古有限调色板，橘、奶油、紫、青绿配色，硬边像素清晰，阴影用抖动处理，方形构图居中，俏皮怀旧的8位游戏氛围。

A 32x32 pixel-art avatar of a chubby orange tabby cat wearing a white astronaut helmet with a golden visor slightly tilted up. Tiny star reflections glint on the glass. The background is a deep-purple space grid with a few bright pixel stars. Limited retro palette of orange, cream, purple, and teal, crisp hard-edge pixels, clear dithering on shadows, centered square composition, playful nostalgic 8-bit game mood.
