Create a clean, futuristic marketing banner in a premium 3D commercial style, designed for an AI app, mobile platform, or startup landing page. Use a soft white-to-light-blue gradient background with a subtle airy glow, lots of negative space, and a polished minimal tech aesthetic. On the left side, place a tall modern smartphone in a slight three-quarter view, with a glossy black frame, realistic screen reflections, and a visible app interface that resembles a social media profile.In front of the phone, position a sleek humanoid robot with a glossy white armored body, black joints, illuminated cyan-blue accents, and a large smooth visor-style face with glowing blue eyes. The robot should be in an energetic forward-running pose, as if stepping out of the phone into the real world, one leg lifted and arms bent dynamically. Give it a friendly but powerful AI assistant look, with detailed mechanical seams, polished surfaces, and high-end sci-fi realism. The robot should feel advanced, helpful, and ready to power a smart app experience.On the right side of the composition, place large bold headline text in a modern rounded sans-serif font, colored deep blue or indigo, aligned left and stacked in three lines: “AI SOCIAL MEDIA AUTOMATION EXPERT” and 'Content • Posting • Full Management'. The typography should be crisp, oversized, and highly legible, with a strong hierarchy and clean spacing. The overall layout should feel balanced and professional, with the robot and phone acting as the visual anchor and the headline as the main message.Use soft studio lighting, realistic shadows under the robot, subtle ambient reflections on the phone, and a light futuristic glow around the subject. Keep the image polished, modern, and app-focused, with a strong sense of innovation, automation, and intelligent digital transformation. The final result should look like a premium AI product ad, startup banner, or SaaS hero image with a sleek, trustworthy, high-conversion visual style.Negative prompt:No clutter, no extra robots, no extra phones, no dark background, no heavy shadows, no neon overload, no chaotic UI, no low-resolution details, no cartoon look, no text distortions, no spelling mistakes, no extra limbs, no broken anatomy, no watermark, no frame, no grain, no messy composition. 16:9 aspect ratio
