YouTube banner design for a channel called 'Topzera'. The banner should be bold, colorful, and energetic, with a modern and playful aesthetic. Include dynamic elements like numbers (10, 5, 3), arrows, stars, icons of curiosity (e.g. light bulb, world, crown), and abstract shapes to suggest countdowns and top rankings. The word 'TOPZERA' should appear large and centered in bold, uppercase, sans-serif font. Add a subtle background with gradients or geometric shapes. Leave space for a circular profile picture on the left. Style should be flat design, high contrast, eye-catching, and optimized for YouTube layout."
