High-Fidelity Fitness Portrait Prompt (Identity Locking)

[Header] (9:16)
Raw high-fidelity photograph, iPhone 17 Pro sensor simulation, professional studio lighting, zero bokeh, SHARP focus from the foreground lavender mat to the background topographic wall panels, f/8 aperture for absolute structural depth, subtle 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 chin structure.
Hair Physics: The hair must exhibit high-definition strand separation, cascading naturally down the back and over the shoulders, reflecting the warm amber backlighting.
Bio-Fidelity: Detailed skin physics including micro-pores, satin-finish hydration, and visible fine vellus hair along the jawline. Precise anatomical rendering of the hands resting on the furniture.
Expression: Magnetic presence; a self-assured, wide smile with high-saturation ruby-red lipstick, directed toward the camera lens.
[Outfit & Physicality]
Technical Description: High-impact technical marl-grey performance-wear set.
Upper Geometry: Long-sleeved compression-fit cropped top with a minimalist crew-neck architecture.
Lower Geometry: Matching high-waisted performance leggings featuring technical shaded textile architecture (contouring lines) that emphasize the gluteal proportions and lower-body silhouette.
Surface Physics: High-tensile material-to-skin surface compression. The fabric must exhibit realistic physical tension lines and micro-knit textures, specifically where it contours the gluteal proportions and proximal limb geometry.
Physicality: Confident self-assured kneeling pose with extreme torso torsion (S-curve). High-fidelity rendering of the anatomical waist-to-hip ratio and symmetrical muscle-to-skin interaction.
[Pose & Composition]
Geometry: High-impact torsion pose. The subject is kneeling on her left knee on a {argument name="mat color" default="lavender"} technical foam mat, leaning her upper body against a neutral-toned bouclé-textured sofa.
Framing: Medium full-shot. The composition is angled to highlight the posterior silhouette and the athletic-to-lean transition characteristic of Image A.
Anatomy: Realistic shoulder-joint displacement as she leans; zero AI distortion in the spinal curve.
[Environment & Lighting]
Atmosphere: Modern minimalist fitness studio or high-end domestic gym.
Interior Details: Lavender-colored technical foam yoga mat on a light-oak hardwood floor. The background features a large topographic abstract wall panel with 3D-contoured textures.
Lighting: Dual-source lighting configuration. A cool-toned front light ensures clarity on the face and textile texture, while a warm amber-to-pink LED backlight creates a glow along the topographic wall and the subject’s silhouette.
Background Integrity: All background architectural elements must remain in sharp focus with zero artificial blurring to maintain a professional photographic aesthetic.
