Technical Pose and Camera Lock Prompt (Swimsuit)

An extremely detailed, technical JSON prompt for Gemini Nano Banana Pro that uses 'lock' parameters to precisely control the subject's pose (body orientation, arm/leg angles, hand gestures), camera settings (focal length, position, distortion), and clothing geometry (one-piece swimsuit with specific text). This prompt is designed for highly controlled image generation.
