Create a vertical social media ad banner that looks like a polished short-video app screen. Feature a young adult lifestyle creator in a close selfie composition, reclining indoors with warm ambient light, soft shadows, long natural hair, a white textured sleeveless top, delicate necklace, and direct eye contact. The framing should crop tightly like a phone video, with the face and upper body filling the center while the background remains softly blurred and intimate. Overlay a complete mobile UI: top status bar, Chinese navigation tabs, search icon, right-side profile, like, comment, favorite, and share buttons with counts, bottom caption text, music tag, and tab bar with a central plus button. Use clean white interface icons, red notification accents, and subtle dark gradient scrims to keep text readable. The mood is casual, aspirational, and social-commerce ready, combining realistic portrait photography with functional ad-platform UI design.
