A square social media profile icon / avatar for the VK community 'Знаниум', crafted in the exact same visual style, lighting, and pastel color palette as the reference banner. In the center, a clean, modern, friendly 3D composition with educational symbols: an open stylized magical book, a glowing lightbulb with subtle brain/gear accents, colorful pencils, and a small graduation cap. Soft glossy claymorphism / 3D illustration style, smooth gradients from vibrant turquoise/cyan to warm pastel yellow in the background, clean composition perfectly centered and readable at small sizes (in a circular crop), studio lighting, high resolution.
