Create a simple, friendly green tree or leaf silhouette for a gardening channel.

Create a stylized silhouette of a green tree or leaf on a light background, representing nature and gardening. The design should be simple, clean, and friendly, suitable for a professional gardening-themed Telegram channel. Use soft, modern shapes with light green tones and a white background to evoke a fresh and inviting feel. Add subtle shading to give depth without complicating the image.
