Use case: identity-preserve
Asset type: square key portrait for a continuous portrait evolution sequence

Primary request:
Using {REFERENCE_FRAME} as the authoritative stage reference, create the level {LEVEL} key portrait of the same Chinese adult man. Preserve his identity exactly: facial structure, glasses, hairstyle, skin tone, age, eye spacing, nose, mouth and overall proportions. Preserve the outfit, expression, posture and stage-specific accessories shown in the authoritative reference. Do not borrow clothing or accessories from a later stage.

Composition and camera:
Photorealistic 1:1 studio portrait, 1024×1024. Full centered half-body composition from the top of the head to the waist or slightly below the waist. The complete head, shoulders, upper arms and torso must remain inside the frame. Keep generous and balanced safety margins on the top, left and right. The head must be clearly smaller than a headshot and must not dominate the frame. Front-facing, eye-level camera, symmetrical posture, 85mm portrait-lens look, no perspective distortion.

Continuity:
Use {PREVIOUS_KEY} and {NEXT_KEY} only as continuity references. Keep eye line, head size, shoulder width, body scale, camera distance, background horizon and light direction consistent across the sequence. Changes from adjacent keys must be gradual and attributable only to increasing intensity. Do not change identity. Do not introduce an intermediate transition pose or motion blur.

Scene and lighting:
Clean full-frame studio background with a subtle neutral gradient appropriate to this stage. The background must fill the entire square evenly; do not bake a left-side blank layout or right-side placement into the image. Soft frontal key light, restrained rim light, realistic skin texture, natural fabric texture, high-end editorial photography.

Constraints:
No close-up crop. No cropped head, shoulders, arms or torso. No side pose. No extra person. No duplicated limbs or accessories. No text, logo, UI, frame, border or watermark. No motion blur. No transition frame. No exaggerated fantasy elements beyond those already visible in the authoritative stage reference. Output only the final square image to {OUTPUT_PATH}.
