YouTube channel banner, 16:9, dark tech background with coral and violet neon glow and subtle grid dots. All important content stays inside a centered horizontal strip (middle 60% width, middle 30% height). In that strip: on the right, the same young Korean man from the reference photo (same face, ash-brown wolf-cut hair, silver earring, black hoodie), shown from chest up, smiling, next to floating small AI-made film frames (a winged lynx in snow, a sci-fi robot army, a Victorian London street). On the left of the strip, large bold Korean title text exactly: "AI 실험실", and below it one smaller line exactly: "AI로 영화, 이미지, 음악까지 직접 만들어 봅니다". Clean modern Korean sans-serif, white title, coral accent on "AI". Correct Korean spelling is critical. Photoreal person, polished YouTube banner design, no other text, no logos.
