+"""规范化构建：表盘源码 + 资源 -> .face（两遍，自动回填 resource.bin 内的偏移）
+
+    main.lua                  <- **源码**，含 __UIIMG__ / __PAY__ / __RB__ / __ROLE__ 占位符
+    .work/overlay/<NAME>      <- 中间产物（回填后的 Lua 落在这里）
+    .work/build/<NAME>        <- 编译工作区
+    dist/<NAME>.face          <- 交付物
+
+两份盘（replace / restore）共用同一套流程，只是负载来源不同：
+    blob_replace/{payload,fp}.bin  ->  S4Chg.face
+    blob_restore/{payload,fp}.bin  ->  S4ChgRestore.face
+rb 表里放的是**另一侧字节前 64 B 的指纹**（只给版本校验用），所以一个 .face 只装一份负载。
