"""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。
