把一张面料糊掉的商拍图修成面料清晰真实的图，构图和人一动不动。
这是一个后处理技能：AI 生成的服装图最容易崩的就是面料——远看还行，放大一看针织变成一片糊。给它一张真实的高清商品图当参照，把表面重建回来。
| 输入：原图（待增强） | 输入：高清商品图（真实面料） |

实际执行的命令：
dlazy gpt-image-2 \
--prompt 'Texture enhancement pass. Image 1 is the on-model photo to improve. Image 2 is the high-resolution product photo that defines the true fabric. Rebuild the sweater surface in image 1 using the real texture from image 2: crisp cable-braid relief, visible knit loops and yarn twist, natural wool loft, correct fold shadows and a matte fibre sheen. Do not change anything else — the model face, hair, hands, pose, brown trousers, background, framing and colour grading must stay identical to image 1. The garment silhouette and colour must not shift; only the material fidelity and micro-detail improve. Photorealistic, sharp, no text, no watermark.' \

输出
example-output.jpg — 1024×1536，60 credits。麻花辫的立体起伏、菱形提花的凹凸、羊毛的绒毛感与褶皱处的暗部层次被重建；模特五官、发型、手部、姿势、棕色长裤、灰墙背景与整体色调保持不变，毛衣轮廓与军绿色未偏移。
| 输入 | 作用 |
|---|---|
| 原图 | 要改善的商拍图，决定构图、模特、姿势、背景与色调 |
| 高清商品图 | 提供真实面料信息（织法、纹理、绒感、光泽） |
| 服装类型 | 帮助判断哪些表面特征该被强化 |
| 只改 | 不改 |
|---|---|
| 面料表面纹理、微观细节、褶皱阴影层次、纤维光泽 | 构图、模特（脸/发/手/姿势）、其他服饰、背景、色调、服装轮廓与颜色 |
不做：不改服装轮廓与颜色；不改模特与背景；不把一种面料换成另一种（换面料请用 fabric-on-body）。
生成前先自检这几条硬性约束：
原图（✅）：构图与人物都满意、只有面料不行的图。
高清商品图（✅）：同一件商品的高分辨率平铺图或特写，能看清织法。
注意事项
| 情况 | 说明 |
|---|---|
| ⚠️ 两张图必须是同一件商品 | 面料不同的两张图会导致材质张冠李戴 |
| ⚠️ 原图颜色如果已经偏了 | 本技能只管纹理，颜色偏差要在生成阶段解决 |
| ❌ 原图崩坏严重（版型错、结构乱） | 材质增强救不了结构问题，重跑生成 |
| ❌ 原图分辨率极低 | 没有足够信息定位纹理该长在哪 |
铁律一：只改表面，别的一个像素都别动。
Do not change anything else — the model face, hair, hands, pose, other garments,
background, framing and colour grading must stay identical to image 1.
The garment silhouette and colour must not shift; only material fidelity
and micro-detail improve.
铁律二：把「好质感」翻译成具体的表面特征，否则模型只会整体加锐化。
| 面料 | 要重建的具体特征 |
|---|---|
| 粗针织 | crisp cable-braid relief, visible knit loops and yarn twist, natural wool loft, matte fibre sheen |
| 精纺羊毛 | fine even weave, subtle fibre halo, soft directional sheen |
| 缎面 | smooth continuous specular gradients along the folds, no texture noise |
| 灯芯绒 | parallel wale ridges with correct pitch, matte pile catching light on the ridge tops |
| 牛仔 | diagonal twill lines, slub irregularity, whiskering at stress folds |
| 皮革 | grain pores, broad soft creases, low-frequency specular sheen |
| 摇粒绒/绒毛 | dense short pile, fuzzy silhouette edge, light scattering rather than specular |
再加一条褶皱层次：correct fold shadows with proper ambient occlusion in the creases——这是「看起来有厚度」的来源。
本技能使用 dLazy 的 gpt-image-2（图像编辑模型 + --quality high；材质增强要求「几何与色彩零变化、表面高频信息重建」，是典型的双图参考定向修复）。
两种等价写法，选一种。统一入口会自动选后端、失败重试、建目录落盘、估算成本：
# A. 统一入口（推荐）：可切任意后端，加 --dry-run 不计费空跑
node scripts/gen.mjs --task material-enhancement \
--prompt '<见下方 Prompt 模板>' \
--images <按下表顺序> \
--save output/material-enhancement-<sku>.jpg
# B. 直接用 dLazy CLI（不想引入 Node 依赖时，效果等价）
dlazy gpt-image-2 --prompt '...' --images ... --save output/material-enhancement.jpg
参数约定（本技能固定用法）
| 参数 | 取值 | 理由 |
|---|---|---|
--images | [原图, 高清商品图] | 顺序即 prompt 中的 image 1 / 2 |
--size | 与原图比例一致 | 增强不该改构图 |
--quality | high（必须） | 本技能的产出就是高频细节 |
--imageFormat | jpeg | 通用格式 |
--batch | 2 | 纹理重建有随机性 |
--save | docs/material-enhancement/output-<sku>-enhanced.jpg | 与原图分开归档便于对比 |

Texture enhancement pass.
Image 1 is the on-model photo to improve.
Image 2 is the high-resolution product photo that defines the true fabric.
Rebuild the [服装部位] surface in image 1 using the real texture from image 2:
[第三节表格里对应面料的具体特征],
correct fold shadows with proper ambient occlusion in the creases.
Do not change anything else — the model face, hair, hands, pose, other garments,

按问题追加的修正句
| 问题 | 追加到 prompt 末尾 |
|---|---|
| 只是整体变锐利了 | This is not sharpening: reconstruct the actual [织法单位] structure, loop by loop, matching image 2. |
| 人脸/背景也变了 | Only pixels inside the garment region may change. Everything outside it must be identical to image 1. |
| 颜色被改了 | Preserve the exact garment colour from image 1; do not shift hue, saturation or brightness. |
| 纹理密度不对 | Match the texture scale to the garment size in image 1: about [N] knit loops per [尺寸]. |
| 褶皱变平 | Deepen the crease shadows with ambient occlusion; the garment must read as [厚度描述] fabric. |
--quality high（必须） → --batch 2 挑图，落盘到 docs/material-enhancement/。| 现象 | 原因 | 处理 |
|---|---|---|
| 只是变锐利了 | 未要求重建结构 | 追加「这不是锐化」句，要求逐个线圈重建 |
| 人脸/背景也被改 | 未锁定区域 | 追加只允许服装区域变化句 |
| 颜色偏了 | 模型顺手调色 | 追加保色句 |
| 纹理密度不对（线圈太大/太小） | 未给尺度参照 | 追加纹理尺度句 |
| 褶皱变平、没厚度 | 缺 AO 描述 | 追加加深褶皱暗部句 |
| 结构崩坏没被修好 | 超出能力 | 本技能只管表面，结构问题回到生成环节重跑 |
