//! 动作链 `tab.actions()` 端到端演示:**拖放**(移到源 → 按住 → 拖到目标 → 释放)。
//!
//! 用本地拖放页(指针式:mousedown 跟随 mousemove 移动方块,mouseup 判断是否落入目标框),
//! 全程离线、确定性强。`HL=0 cargo run --example actions_drag --no-default-features --features camoufox` 可开窗口观看。
//!
//! 运行:`cargo run --example actions_drag --no-default-features --features camoufox`(默认 headless;`HL=0` 看界面)
//! 末行打印 `ALL CHECKS PASSED` / `SOME CHECKS FAILED`。
