Create one vertical 9:16 image as a 4 by 4 grid of 16 connected square panels, forming a dance choreography breakdown chart for the original or authorized Japanese idol dance song [Song Title] ([Romanized Title]). This chart is a pose reference for AI video generation, so every full-body pose must be clear, uncropped, and easy to read. The same [Character] must appear in all 16 panels, with identical face, hairstyle, outfit, proportions, and colors. Use original half-realistic anime idol illustration styling with clean line art, soft cel shading, vivid colors, and no direct imitation of any existing idol franchise. Each cell has thin black grid lines, a plain [Background Color] background, a centered full-body straight-on eye-level pose, a numbered circle in the top-left, and a small Japanese pose caption on a white strip at the bottom. Panel 1 arms spread wide; 2 point upward; 3 overhead heart hands; 4 hip sway S-curve; 5 blowing a kiss; 6 kneeling on one knee with hands near chin; 7 hands crossed over chest; 8 mid-spin turn; 9 flowing arm wave; 10 joyful jump; 11 arms crossed in an X; 12 double peace signs; 13 signature finish pose; 14 both hands waving overhead; 15 low crouching pose; 16 grand finale V pose. Put a clean bold header at the top reading “[Header Text]”. Keep pose silhouettes crisp and unambiguous, prioritizing pose clarity over decoration. Avoid real song branding unless authorized, copyrighted idol-franchise references, copied character designs, minor-coded sexualization, lewd framing, studio logos, watermarks, speech bubbles, extra characters, cropped limbs, broken grid lines, overlapping panels, motion blur hiding the body, extra fingers, unreadable Japanese text, QR codes, URLs, and signatures.
