## 角色选择：左边一个 3D 预览（慢慢自转），右边挑角色和脸。
|
||||
##
|
||||
## 预览里这具模型和玩家场景里的模型是**两套独立的 FaceRig**，但共用同一份存档：
|
||||
## 这里点「确定」写进 user://，玩家出生时自己的 FaceRig.apply_saved() 读回来。
|
||||
##
|
||||
## 目前只有一个角色模型（mouse.glb），所以角色那一栏只有一个按钮 ——
|
||||
## 以后加了新模型，往 CharRow 里再放一个按钮就行。
|
||||
## 角色选择：预览模型、内置表情 atlas 与玩家本地表情库。
