Full YouTube channel banner image, high resolution. In the far distance, a blurred (bokeh) landscape of a modern Brazilian city square with clean, symbolic architecture and a warm blue sky, rendered in a professional, soft educational digital painting style using gentle green and yellow tones. In the center-right of the banner, a detailed, high-quality 3D Pixar-style render of the Brazilian man from image_4.png (short curly dark hair, beard, clear eyeglasses, green t-shirt with Brazil flag patch) is positioned, smiling and gesturing warmly with one hand as if explaining a concept. A direct replica of the 'POLÍTICA SEM MISTÉRIO' text banner from image_4.png is placed in the center-left. This banner is framed by a glowing soft teal line, and subtle 3D icons (such as a gavel, a voting box, a stylized senate building, and an open book) float around it, connected by faint, educational light paths. Below the main text banner, in clean white text, it says: 'Aulas simplificadas para todos'. The overall composition is clean, balanced, and uses a soft, non-intrusive light, ensuring text legibility and maintaining the welcoming, intelligent aesthetic. The background city is distinct but heavily blurred to focus on the avatar and text. The colors are consistent with the soft teal, green, and yellow theme of the logo.
