CHARACTER LOCK — HIGHEST PRIORITY: The person in every shot is exactly the person in @image1. Preserve their facial identity, facial structure, eye shape and spacing, nose, mouth, exact skin tone, hairline, hairstyle, hair length, texture and colour, freckles and distinctive marks, apparent age, build and body proportions — identically, shot to shot. Preserve their gender presentation exactly as shown; do not masculinize, feminize or reinterpret it. Do not beautify, slim, de-age or restyle them. The attached image outranks every word below it: wherever the image and the text disagree, follow the image. Frame 1 is already in the scene — never a studio portrait, grey backdrop, or the attached still as an opening plate. Use they/them throughout. No other people. The person in every shot is exactly the person in @image1 — face, bone structure, skin, blonde hair, age, body. The photo is identity only, not wardrobe. Do not keep the ivory blazer, camel skirt, boots or bag from the photo. Do not give them black hair. WARDROBE (from the source film): butter-yellow cropped t-shirt with a silver rhinestone star, black neck trim, beaded fringe at the hem; distressed blue denim shorts; thin black belt; layered silver necklaces; white crew socks with stripes; chunky silver-white sneakers. Same outfit for the full 15 seconds. SETTING: charcoal-grey seamless studio, dry floor with a faint reflection. No furniture, no crowd, no props. Soft white key from front-left, pale blue-violet rim from behind. One person only. No on-screen text. MUSIC: 128 BPM four-on-the-floor k-pop dance track already in the chorus. Heavy kick, bouncing bass, sharp claps. No intro, no fade-out, no ending hit. The clip is a mid-routine slice — they are already dancing in frame 1 and still moving in the last frame. CHOREOGRAPHY — one continuous 15s routine in four phrases. Never freeze. Never a start pose or a finish pose. Phrase 1 (0–3.75s): already weighting the left leg as arms return to the chest. Step hard right, uncross the arms out and open the chest. Weight back left, arms circle down. Two small forward steps, a sharp chest hit on the clap. Open the right foot, drop the knees, arms to the hips into a hip figure-eight. Phrase 2 (3.75–7.5s): low hip figure-eight, weight right-left-centre. Wave up from pelvis through belly to chest. Uncoil the arms as the right foot crosses in front, glance at the lens with a brief smile without stopping. Phrase 3 (7.5–11.25s): smooth stepping turn, hair lagging the spin. Land into a right side lunge, left arm high, long diagonal. Push back to centre, wave down the torso. Phrase 4 (11.25–15s): two strong hip accents. Two quick steps to centre, load the arms. Open the right foot wide, big arm unfold — not a finish, a send-off. Circle the arms down, take weight on the left, right foot already starting the next cross-step. Last frame still travelling. CAMERA (cut on the body, never reset the step): 0–3.75s full body, slight three-quarter, short lateral slide. 3.75–5.625s waist-up, hip figure-eight, locked frame. 5.625–7.5s face and shoulders, 85mm, the wave hitting the collarbone. 7.5–11.25s full body for the turn and lunge. 11.25–13.125s head to mid-thigh. 13.125–15s full body, short lateral move, no zoom-in to end. Photoreal skin, light sweat, motion blur on hair and hands. No slow-mo, no logos, no extra limbs.
