High-Fidelity Mirror Selfie Prompt with Identity Locking

[Header] (9:16) Raw high-fidelity photograph, iPhone 17 Pro sensor simulation, indoor ambient lighting, zero bokeh, SHARP focus from the foreground textile folds to the background wall, f/5.6 aperture for structural clarity, 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 chin structure. Bio-Fidelity: Detailed skin physics (micro-pores, satin-finish hydration, and visible fine vellus hair along the jawline). Precise rendering of the collarbone and upper-torso symmetry. Expression: Mirror-selfie aesthetic; the face is partially obscured by the technical device, capturing a focused and magnetic gaze toward the reflection. [Outfit & Physicality] Technical Description: High-impact technical micro-romper in a matte onyx black performance textile. Textile Geometry: Off-the-shoulder architecture with a straight horizontal neckline and full-length compression-fit sleeves. Accessories: Minimalist silver cross-shaped drop earrings; delicate silver-link chain necklace with a small circular pendant. Surface Physics: High-tensile material-to-skin surface compression. The fabric must exhibit realistic physical tension lines as it contours the anatomical bust volume and emphasizes a pronounced hourglass S-curve silhouette. Physicality: Confident self-assured seated posture, highlighting the waist-to-hip ratio and symmetrical proximal limb geometry of the upper thighs. [Pose & Composition] Geometry: Full-body seated mirror-reflection framing. The subject is sitting upright on the edge of a bed, legs positioned symmetrically and forward. Framing: Vertical 9:16 orientation. The subject holds a dark technical smartphone centrally at face level, capturing the reflection in a full-length mirror. Anatomy: Realistic shoulder-joint displacement and upper-body symmetry, reflecting the athletic-to-lean transition characteristic of Image A. [Environment & Lighting] Atmosphere: Minimalist domestic interior (bedroom). Interior Details: The subject is seated on a white bed with high-detail quilted linens and realistic fabric folds. The background is a clean, neutral-toned flat-painted wall. Lighting: Diffused {argument name="lighting temperature" default="3500K warm"} indoor lighting. The light source provides even illumination across the skin and the black textile, creating soft shadows that define the muscle-to-skin interaction in the legs. Background Integrity: All background architectural elements and bedding textures must remain in sharp focus with zero artificial blurring. [Failure Prevention Rule] Command: Use "Technical off-the-shoulder micro-romper" and "Full-length compression-fit sleeves" to ensure the AI maintains the exact garment fit. Constraint: Explicitly command "Zero artificial bokeh" and "Sharp focus on bedding texture" to ensure the photo maintains an authentic smartphone aesthetic. Specify "Anatomical bust vo
