- 根因：~Application 体内 Logger::Shutdown() 先于成员析构执行， Device 销毁期间 Vulkan validation 回调仍打日志 → spdlog 悬空调用 - 修复：app 置于 main 独立作用域，所有成员析构完毕后再 Shutdown - 退出序 = waitIdle（~Application 体内）→ 成员析构（shader 等 Device 子对象销毁）→ Logger::Shutdown - 顺带注释掉窗口全透明（调试期遗留）

// SandboxApp：第一个基于 Application 框架的程序。
|
||
//
|
||
// main 的职责边界：
|
||
// - 定义 Application 派生类并运行它
|
||
// - "程序逻辑"：场景搭建（实体/组件）、逐帧更新、事件响应、
|
||
// 异步环境加载
|
||
// - UI 全部委托 App/editor/ 的 docking Editor（本文件不再出现
|
||
// 任何 ImGui 控件）
|
||
//
|
||
// 窗口、渲染器、事件泵、帧计时、场景容器全部由框架管理。
