Korean tech YouTube thumbnail, high contrast, bold and simple. Left third: the same young Korean man from the reference photo (same face, ash-brown wolf-cut hair, silver earring, black hoodie), chest-up, big surprised open-mouth expression, pointing to the right. Right two-thirds: three cinematic AI film frames stacked in a slight fan (a giant winged lynx in snow, an army of cybernetic animals on a burning slope, a monster rising under snowy Victorian London), each with a small red "원본" vs coral "AI" corner label. Huge bold Korean headline across the top right, exactly: "한 문장으로 만든 영화". Smaller yellow line under it, exactly: "조회수 600만 영화 따라잡기". Dark background with coral and violet neon glow. Correct Korean spelling is critical. No other text, no logos.
