Create a YouTube channel banner for a children's channel called "Leo's World: Safety & Magic". Wide 2560x1440 format. The banner shows the main character Leo (cute 3-year-old American toddler boy, brown hair, blue eyes, yellow t-shirt, blue wizard hat) in the center. On the left side: Leo wearing a safety helmet and holding a stop sign (safety theme). On the right side: Leo casting a golden spell with his wand (magic theme). Background is a magical sky with soft clouds and sparkles. Style: 3D Pixar animation, hyper-realistic textures, bright and cheerful colors. Leave empty space in the center for text overlay. No text, no letters, no words.
