"""为官方 LuaDevTemplate 生成可编译的 overlay。两份盘：S5Chg（替换）/ S5ChgRestore（还原）。
|
|||
|
|
|
|||
|
|
要点（都是踩过的坑）：
|
|||
|
|
* Compiler.exe 的设备表里没有 480 档 -> 用 DeviceType=462（S5 家族，圆表）+ 480x480 的
|
|||
|
|
Screen；preview.png 必须是 326x326，别的尺寸直接拒绝
|
|||
|
|
* 预览图按 tools/pages.py 的首页规格真渲染（真 MiSans 字体）再套圆形 alpha 缩到 326
|
|||
|
|
* 两份盘共用同一个 watchface id 462150103：装一份就顶掉另一份
