/// ============================================================
|

/// 闲言APP — 延迟渲染包装组件
|
||
/// 创建时间: 2026-06-02
|
||
/// 更新时间: 2026-06-02
|
||
/// 作用: 将子组件(如syncfusion chart)延迟到postFrameCallback渲染
|
||
/// 避免chart在build阶段触发markNeedsLayout导致卡死/闪退
|
||
/// 内置RepaintBoundary隔离重绘，避免图表重绘波及父级
|
||
/// 上次更新: 增加RepaintBoundary隔离 + 可选placeholder + mounted安全检查
|
||
/// ============================================================
