[标题] (9:16) 原始高保真照片，iPhone 17 Pro 传感器模拟，高角度俯视视角，零散景，从前景草地纹理到背景建筑物的锐利对焦，f/8 光圈实现整体结构深度，真实的数字颗粒。 [主体与身份锁定] •身份：绝对保留图像 A 的特定面部几何结构，强调杏仁状眼睛、丰满的嘴唇和清晰的下颌线。 •发型物理：长而浓密的编织马尾辫，由深巧克力色波浪纹理构成，用黑色技术发带固定。帽子下方头发束起处可见高清晰度的毛囊细节和发丝纹理。 •生物保真度：详细的皮肤物理（微孔、缎面光泽水润）。逼真呈现侧面颈部结构和下颌线对称性。 •表情：极具魅力；自信的目光向上并稍微偏离镜头，捕捉真实的跑后运动美学。 [服装与体态] •技术描述：高性能单色运动服。 •上身几何：哑光缟玛瑙黑色长袖技术压缩贴身半拉链上衣。 •下身几何：哑光黑色技术高切高性能短裤，展现逼真的材料与皮肤表面压缩效果。 •配饰：黑色技术棒球帽，带有白色“NY”标志；白色技术无线耳机（AirPods 风格）；左手腕佩戴白色技术智能手表。 •体态：运动型近端肢体几何；下蹲姿势强调了对称的股四头肌线条。 [姿势与构图] •几何：高角度俯视“下蹲”自拍。主体在草地上完全下蹲，右臂伸向镜头以捕捉画面。 •构图：垂直 9:16 构图。构图利用广角视角包含主体身体和周围环境。 •解剖：逼真的膝关节屈曲和小腿与大腿的压缩。伸出的自拍手臂必须展现自然的肌肉与皮肤互动以及肩关节位移。 [环境与光照] •氛围：公园或郊区住宅绿地。 •背景完整性：一条红色调的技术表面跑道蜿蜒伸向远方。背景特征为光秃的落叶乔木和白色多层现代住宅建筑。前景的草地郁郁葱葱，散落着棕色的秋叶。 •光照：中性漫射 5500K 日光。光源在皮肤和黑色纺织品上提供一致的照明，形成柔和的阴影，勾勒出主体的解剖轮廓。 [失败预防规则] •指令：使用“Technical compression-fit athletic top”（技术压缩贴身运动上衣）和“High-cut performance-wear shorts”（高切高性能短裤）以确保 AI 保持精确的合身度和长度。 •限制：明确指令“Zero artificial bokeh”（零人工散景），以确保远处的公寓楼和红色跑道保持完美清晰。指定“Anatomical thigh symmetry”（解剖学大腿对称性）以确保大腿
[Header] (9:16) Raw high-fidelity photograph, iPhone 17 Pro sensor simulation, high-angle downward perspective, zero bokeh, SHARP focus from the foreground grass textures to the background architecture, f/8 aperture for total structural depth, authentic digital grain. [Subject & Identity Locking] •Identity: Absolute preservation of Image A’s specific facial geometry, emphasizing the almond eye shape, high lip volume, and defined jawline. •Hair Physics: Long, thick braided ponytail composed of dark chocolate textured waves, secured with black technical bands. High-definition follicle detail and hair texture visible where the hair is pulled back under the cap. •Bio-Fidelity: Detailed skin physics (micro-pores, satin-finish hydration). Realistic rendering of the side-profile neck architecture and jawline symmetry. •Expression: Magnetic presence; a self-assured gaze directed upward and slightly off-camera, capturing an authentic post-run athletic aesthetic. [Outfit & Physicality] •Technical Description: High-performance monochromatic athletic-wear. •Upper Geometry: Long-sleeved technical compression-fit half-zip top in matte onyx black. •Lower Geometry: Technical high-cut performance-wear shorts in matte black, showing realistic material-to-skin surface compression. •Accessories: Black technical baseball cap with a white "NY" logo; white technical wireless earbuds (AirPods style); white technical smartwatch on the left wrist. •Physicality: Athletic proximal limb geometry; symmetrical quadricep definition emphasized by the crouching pose. [Pose & Composition] •Geometry: High-angle downward "squat" selfie. The subject is in a full crouch on a grass surface, right arm extended toward the lens to capture the shot. •Framing: Vertical 9:16 orientation. The composition uses the wide-angle perspective to include the subject’s body and the surrounding environment. •Anatomy: Realistic knee-joint flexion and calf-to-thigh compression. The extended selfie arm must show natural muscle-to-skin interaction and shoulder-joint displacement. [Environment & Lighting] •Atmosphere: Public park or suburban residential green space. •Background Integrity: A red-toned technical-surface running track curving into the distance. Background features bare deciduous trees and white multi-story modern residential buildings. The grass in the foreground is lush green with scattered brown autumn leaves. •Lighting: Neutral diffused 5500K daylight. The light source provides consistent illumination across the skin and black textiles, creating soft shadows that define the subject’s anatomical contours. [Failure Prevention Rule] •Command: Use "Technical compression-fit athletic top" and "High-cut performance-wear shorts" to ensure the AI maintains the exact fit and length. •Constraint: Explicitly command "Zero artificial bokeh" to ensure the distant apartment buildings and the red track remain perfectly crisp. Specify "Anatomical thigh symmetry" to ensure t
