Seated Portrait Pose Estimation Overlay

Goal: Create a photorealistic portrait overlaid with a pose-estimation / 3D block-model visualization, as if analyzing a seated human body with cuboid volumes aligned to a floor grid.

Canvas: Vertical 4:5 image, soft natural daylight, realistic camera photo look. Indoor minimalist living room with pale wall, light wood floor, and a cream rug in the foreground. In the left background, include one wooden shelving unit with white books and woven baskets, plus one leafy green houseplant above it.

Main subject: A young East Asian woman, about early 20s, sitting on the floor facing the camera in a compact curled pose. She has {argument name="hair color" default="dark brown"} long straight hair with wispy bangs, natural makeup, warm eyes, and a gentle slight smile. She wears a loose {argument name="top color" default="cream white"} long-sleeve sweater, blue jeans, white socks, and no shoes. Her knees are pulled up close to her chest, arms wrapped around her shins, feet together near the bottom center, body leaning slightly to one side while maintaining eye contact with the camera.

Overlay: Add a semi-transparent technical 3D pose-estimation diagram over the photograph. Use thin brown-gray wireframe cuboids and translucent teal-blue rectangular prisms to approximate the body volumes. Count and show exactly 13 major cuboid body blocks: 1 head block, 1 neck block, 1 torso block, 1 pelvis/hip block, 2 upper-arm blocks, 2 forearm blocks, 2 thigh blocks, 2 lower-leg blocks, and 2 foot blocks. The blocks should be imperfectly aligned but plausibly matched to the seated pose, with visible perspective lines, overlapping transparent faces, and wireframe edges. Include a faint perspective floor grid in pale blue-purple lines, matching the room floor and receding toward the background.

Label: At the top left, place one rounded white translucent label bar with Japanese text exactly: {argument name="overlay label" default="直方体モデルの重ね合わせ｜グリッドと同じ1単位"}. The label should use a small clean sans-serif font, dark gray text, and sit slightly inset from the image edge.

Visual style: realistic high-resolution lifestyle photography blended with analytical AR overlay, soft shadows, shallow depth of field, calm domestic atmosphere, clean composition, no watermark, no extra labels or diagrams beyond the single top-left label and the cuboid/grid overlay.
