未在一张图里直接画三视图，而是按 imagine / game-character-consistency 的编辑链：先从参考图派生正面，再从正面派生侧面与背面，最后用 ffmpeg 拼接。
ref-原图.png，记录不对称特征（发饰左右）。image_edit：参考图 → 正面全身站姿（第 1 版，领口偏高领，未采用为最终正面）。image_edit：第 1 版正面 → 修正领口为露肩（第 2 版，采用为 front.png）。image_edit：第 2 版正面 → 严格侧面（采用为 side.png）。image_edit：第 2 版正面 → 严格背面（第 1 版背面，脚下有浅影）。image_edit：第 1 版背面 → 去掉地面投影（第 2 版背面，采用为 back.png）。#F7F7F7（避免白边与浅灰底形成拼缝）。hstack 横向拼接为 turnaround-3view.png。共调用 image_edit 5 次（无 image_gen）。最终采用 3 张面板；另有 2 次针对性重试（领口、投影）。
以角色自身左右为准：
| 视图 | 深蓝蝴蝶结出现位置 | 白色小花出现位置 |

| 正面 | 画面左侧（角色右） | 画面右侧（角色左） |
| 左侧面（面朝左） | 远侧马尾上，可见于脑后发束 | 近侧，耳旁清晰可见 |
| 背面 | 画面右侧（角色右） | 画面左侧（角色左） |
Keep this exact Japanese anime-style girl as the same character: long waist-length purple hair fading to lavender at the tips in twin tails, pale-purple cat ears with white inner fur, magenta-pink eyes, a small dark-blue bow on the right side of her head (viewer's left) and a small white flower hair accessory on the left side of her head (viewer's right), blue denim shorts with ruffled hems, white ruffled ankle socks and simple white shoes. Change only the dress neckline: replace the high collar with a true off-shoulder white ruffled dress like the reference, collarbones and shoulders exposed, a tiny dark-blue ribbon at the center of the open neckline, white buttons down the bodice, ruffled short sleeves, iridescent rainbow pearlescent sheen on the skirt. Keep the same calm A-pose, full body from cat-ear tips to shoes, peaceful expression, clean Japanese anime illustration, cel-shaded, even studio lighting, solid pure white background, isolated character, no props, no gift box, no scene, no cast shadow, no text.Keep this exact Japanese anime-style girl as the same character: long waist-length purple hair fading to lavender at the tips in twin tails, pale-purple cat ears with white inner fur, magenta-pink eyes, a small dark-blue bow on the right side of her head and a small white flower hair accessory on the left side of her head, white off-shoulder ruffled dress with iridescent rainbow pearlescent sheen and ruffled short sleeves, a tiny dark-blue ribbon at the neckline, blue denim shorts with ruffled hems, white ruffled ankle socks and simple white shoes. Rotate her into a strict full-body RIGHT PROFILE character-turnaround panel: she faces the left edge of the frame, nose chest and toes all pointing left, we see her right side so the dark-blue hair bow is on the near side of the head and the white flower is hidden on the far side. Same calm standing A-pose, arms hanging naturally slightly away from the body, peaceful neutral expression, entire figure visible from cat-ear tips to shoes. Clean Japanese anime illustration, cel-shaded, even studio lighting, solid pure white background, isolated character, no props, no gift box, no scene, no cast shadow, no text.说明：提示词写了 RIGHT PROFILE，模型实际产出的是左侧面（面朝左、近侧为白花）。任务允许任选一侧，故保留左侧面，未再重抽。
去阴影前的旋转提示词：
Keep this exact Japanese anime-style girl as the same character: long waist-length purple hair fading to lavender at the tips in twin tails, pale-purple cat ears with white inner fur, a small dark-blue bow on the right side of her head (now appears on the viewer's right) and a small white flower hair accessory on the left side of her head (now appears on the viewer's left), white off-shoulder ruffled dress with iridescent rainbow pearlescent sheen and ruffled short sleeves, a tiny dark-blue ribbon at the neckline, blue denim shorts with ruffled hems, white ruffled ankle socks and simple white shoes. Rotate her into a strict full-body BACK VIEW character-turnaround panel: she stands with her back fully to the camera, we see the back of the head, both cat ears from behind, twin tails hanging down her back, the back of the off-shoulder dress and denim shorts. Same calm standing A-pose, arms hanging naturally slightly away from the body so the outfit silhouette is clear, entire figure visible from cat-ear tips to shoes. Clean Japanese anime illustration, cel-shaded, even studio lighting, solid pure white background, isolated character, no props, no gift box, no scene, no cast shadow, no text, no face visible.去阴影提示词：
Keep this exact Japanese anime-style girl back view completely unchanged: same pose, same long waist-length purple twin tails fading to lavender, pale-purple cat ears with white inner fur, small white flower hair accessory on the viewer's left and small dark-blue bow on the viewer's right, white off-shoulder ruffled dress with iridescent rainbow pearlescent sheen, blue denim shorts with ruffled hems, white ruffled ankle socks and white shoes. Change only the background: remove the gray ground shadow under the feet and fill the entire background with a flat solid very light gray, no shadow, no floor, no props, no text.

turnaround-3view.png| 次数 | 操作 | 结果 | 处理 |
|---|---|---|---|
| 1 | image_edit 参考图 → 正面 | 全身 A-pose、特征齐全，但领口变成高领/蕾丝立领，与原图露肩不符 | 不采用为最终正面；再 edit 一次只改领口 |
| 2 | image_edit 正面 v1 → 露肩修正 | 肩颈更接近原图，仍保留颈前深蓝丝带（三视图内统一） | 采用为 front.png |
| 3 | image_edit 正面 → 侧面 | 得到严格左侧面（非 3/4 正面），特征与服装一致 | 采用为 side.png（任务允许任选一侧） |
| 4 | image_edit 正面 → 背面 | 背面旋转正确、发饰左右符合 180° 旋转而非镜像；脚下有浅灰投影 | 再 edit 一次只去投影 |
| 5 | image_edit 背面 v1 → 去阴影 | 投影去掉，角色未漂 | 采用为 back.png |

未采用「一张图直接画三视图」。未使用 image_gen 凭空重画。
