"A gender-neutral avatar concept for a chatbot featuring only a silhouette or shadow. The shadow is soft and smooth, with no facial details, avoiding any gender-specific features. The shape of the head and shoulders is balanced, simple, and neutral. The design uses a clean, futuristic background with soft gradients in gray or white to make the silhouette stand out. The overall look is modern, minimalistic, and professional, suitable for universal representation in digital interfaces."
