现象（用户反馈）：导入 PMX 转换出的 GLB 后，列表页/审核面板里的模型是白模， 脸部颜色信息全部丢失。 定位过程（本地装真 Assimp 6.0.4 + 该模型完整复现）： 1. 转换本身正常：23.7MB GLB、643 骨骼、93,350 面； 2. 18 张贴图逐字节与压缩包原图一致；用一个权威 PMX 解析器比对后确认 39 个材质 -> 贴图的对应关系与 PMX 完全一致（不是映射错）； 3. UV 采样也正确：脸部材质取到的就是皮肤色 (246,221,216)； 4. 真正的问题在**我们自己的缩略图渲染器**：它刻意不解码 baseColorTexture， 只用 baseColorFactor 上色（见文件头取舍说明）；而 MMD 模型的 baseColorFactor 基本都是白色 -> 缩略图必然全白。管理端 3D 预览有贴图， 只有列表/审核的缩略图是白的。 修复： 1. model-thumbnail.ts 内置极简 PNG 解码器（zlib inflate + 逐行反滤波， 8 位非隔行，colorType 0/2/3/4/6），按 baseColorFactor x 贴图逐像素采样， 透视校正 UV；解码失败/非 PNG/隔行扫描回退纯色，绝不抛错； 2. 按 alphaMode 处理透明度：OPAQUE 忽略贴图 alpha（MMD 语义）、 MASK 按 alphaCutoff 丢弃、BLEND 做 source-over； 3. 取景收紧 FRAMING 1.6 -> 1.3，40px 列表缩略图主体更清楚； 4. 新增 test/model-thumbnail-texture.spec.ts 6 项（含白模回归： baseColorFactor 全白 + 红贴图必须输出偏红，以及 MASK/OPAQUE/坏图回退）； 5. 版本 0.2.4，README(.md/.txt)/DSH.md 补修订说明与 FAQ（含重新生成缩略图 的 reanalyze-models.mjs --force 命令）。
