Key conflict fix (UE semantics): while RMB is held the keyboard belongs to the camera, so WASD no longer collides with the gizmo W/E/R tool hotkeys. Editor mode gates fly movement behind RMB; game mode keeps always-on WASD. Viewport tool hotkeys (W/E/R/T/F) are suppressed while RMB is held. Focus orbit (pivot): MMB drag rotates the camera around a pivot keeping distance; first orbit picks a pivot 5m ahead on the view ray. Shift+MMB pans in screen plane (camera and pivot move together). Mouse wheel dollies toward/away from the pivot with exponential steps (no pivot: move along view ray). F focuses the selected entity (frame-selection): pivot set to its position, camera slides along the view ray; orbit distance persists. Window gains a polled scroll-delta channel (ConsumeScrollDelta) that respects ImGui mouse capture; Camera::Update mutates orbit state (no longer const).

// 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。
