+# Asset Pipeline · TOS 桶资源压缩 + 打包
+
+把 `public/portraits/` 和 `public/videos/` 转成桶友好的体积（WebP + H.264），输出到仓库外的 `../assets-compressed/`。
+
+## 输出结构（与桶目录对齐）
+
+```
+assets-compressed/
+├── portraits/
+│   ├── 001.webp
+│   ├── 001-2.webp
+│   ├── 001-3.webp
+│   ├── 001-view.webp
+│   └── ...
+└── videos/
+    ├── hero-pv.mp4
+    └── artists/001.mp4 ...
+```
+
+## 压缩参数
+
+| 类型 | 处理 | 目标体积 |
+|---|---|---|
+| 立绘 / 氛围图 PNG | WebP q82, 最大宽 1600 | ≤ 800KB |
+| 三视图 `-view.png` | WebP q82, 最大宽 2400 | ≤ 1.5MB |
+| 视频 MP4 | libx264 CRF 28, 最大宽 1920, AAC 96k, faststart | 单条 ≤ 3MB / Hero PV ≤ 15MB |
+
+## 用法
+
+```bash
+cd tools/asset-pipeline
+npm install           # 装 sharp + ffmpeg-installer (各自带二进制, 无需系统装)
+npm run compress      # 压缩, 已存在且新于源的输出会跳过 (可恢复中断)
+npm run pack          # 打包成 cyber-star-assets.tar.gz
+```
+
+输出文件：
+
+```
+../../assets-compressed/                # 压缩后的源文件 (供回滚 / 抽查)
+../../cyber-star-assets.tar.gz          # 发给运维上传的最终包
+```
+
+## 上传到桶
+
+运维拿到 `cyber-star-assets.tar.gz` 解压后，用 tosutil 整目录推：
+
+```bash
+tar -xzf cyber-star-assets.tar.gz
+tosutil cp -r -f assets-compressed/* tos://cyber-star/
+```
