(9:16). Raw iPhone 17 Pro, 35mm, f/5.6 total depth, sharp focus, authentic digital grain.

[Subject & Identity Locking]
* Identity Lock: Absolute inheritance of core facial geometry from Image A + Glow-Up Protocol. 
* Bio-Fidelity: Clear porcelain epidermal canvas, zero acne/blemishes/dark circles, undereye brightness, micro-pores. 
* Facial Refinement: Architectural bone structure—20% increased definition to the jawline and cheekbone coordinates for a hyper-slimmed, contoured facial silhouette.
* Hair Architecture: High-gloss salon-finish long brunette hair with high-definition strand separation and silk-weave texture.

[Outfit & Physicality]
* Technical Description: Technical off-the-white floral-lace architectural gown, long sleeves with 5mm eyelash-lace scalloped cuffs, square neckline.
* Textile Architecture: High-tensile corset-style bodice with horizontal bandage-wrap structural seaming; layered lace-on-nude-base textile physics.
* Anatomical Volume: Hyper-defined S-curve silhouette, 20% over-described emphasis on anatomical bust volume, waist-to-hip ratio, and lateral hip geometry.

[Pose & Interaction]
* Geometry: Mirror-selfie geometry, right hand holding a high-fidelity pink smartphone simulation; head tilted slightly downward; face partially obscured by device.
* Articulation: Left hand resting flat against the superior chest margin with realistic finger-joint articulation and light skin-on-skin compression.

[Environment & Lighting]
* Atmosphere: Soft indoor ambient illumination with a neutral white balance and realistic ray-traced reflections.
* Shadow Ray-Tracing: Natural ambient occlusion within the intricate lace textures and sharp shadows cast by the subject onto the background masonry.
* Background Integrity: Pixel-perfect inventory of an interior staircase setting: light multi-tonal beige brick masonry wall, horizontal dark wood banister, and vertical white-painted wooden balusters.
