"""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__ 占位符
|
|||
|
|
.work/overlay/S5Icons <- 中间产物（回填后的 Lua 落在这里）
|
|||
|
|
.work/build/S5Icons <- 编译工作区（Compiler.exe 的实际输入）
|
|||
|
|
dist/S5Icons.face <- 交付物
|
|||
|
|
|
|||
|
|
为什么要两遍：.face 里各资源的偏移取决于打包顺序，我们靠在 .face 里搜文件字节来定位。
|
|||
|
|
Lua 源码排在所有资源**之后**，所以回填（让 Lua 变长）不会移动前面资源的位置 —— 第一遍量出来的
|
|||
|
|
偏移在第二遍依然成立，脚本最后会逐条校验。
