Create a 9:16 vertical smartphone screenshot for a brand-neutral short-video social app. The theme is an entry-level AI learning course promotion: catching up with the AI wave, a low-cost trial price, zero-foundation learning, practical AI tool operation, quick onboarding, and application-to-income thinking. Compose it like a creator content screen with a young adult female presenter in a warm desk setup, a monitor showing a generic AI-themed graphic, large bold Chinese headline typography, yellow-and-white high-contrast promo text, checklist-style benefit labels, right-side social action icons, a creator handle area, and a short caption near the bottom. Keep it as an illustrative education-promo UI mockup, not a real checkout page and not a guaranteed income claim. Use a smartphone-style vertical interface without any real phone brand, platform logo, app name, trademark, QR code, payment link, or copied Douyin/TikTok marks. Text should be legible, original, and clearly promotional while avoiding false guarantees, exaggerated income promises, real teacher identity, real brand names, copied UI logos, underage appearance, or misleading certification claims. Output aspect ratio: 9:16.
