变更

  • 普通弹窗、确认框和抽屉的遮罩取消入场淡入动画。
  • 遮罩仍保留出场淡出动画，弹窗和抽屉本体动画不变。
  • 全屏模糊遮罩在挂载时即进入终态，避免入场期间逐帧重新计算整窗模糊。
  • 在游戏占用 GPU 等高负载场景下减少打开弹窗时的掉帧。

验证

  • 页面岛与手机端 TypeScript 检查、页面岛主界面与登录页构建、手机端构建均通过。
  • git diff --check：通过。

说明

  • 本 PR 基于官方 beta 的 aba58858 重新整理。
  • 仅调整 ui-kit 三种遮罩的入场动画类名，并同步页面岛构建产物。

Summary

1. 📌 通俗总结（这个 PR 做了什么？）

普通弹窗、确认框和抽屉的遮罩打开时不再播放淡入动画，挂载后直接显示。关闭时仍保留淡出动画，弹窗和抽屉本体的动画没有改动。

这样可以避免带全屏模糊效果的遮罩在入场动画期间逐帧重算背景，降低高负载设备打开弹窗时掉帧的风险。页面岛和手机端的构建产物也同步更新，手机端 Service Worker 的缓存版本随之变更。

2. 💡 产品与技术方案评估

这是针对高负载场景的体验优化。改动集中在遮罩动画，没有改变弹窗的关闭方式或主体动画，范围清楚，风险相对可控。

技术方案直接移除了遮罩的入场动画，针对的是模糊效果可能带来的重复计算，优于只缩短动画时间。不过，打开时遮罩会立即出现，视觉上可能比弹窗主体更突然。建议在低端设备和高负载场景验证掉帧是否改善，并检查遮罩与主体动画不同步时是否影响观感。

当前证据能确认代码和构建产物已更新，但没有当前 HEAD 上的检查结果可供核实。

三个弹窗遮罩不再使用打开时的淡入动画，关闭动画保持不变。Service Worker 的缓存名称已更新。

重新生成并提交手机端产物

手机端打开“社区与支持”时，遮罩仍会淡入，高负载下仍可能掉帧。已提交的手机脚本中，另外两种遮罩也保留了旧类。运行 npm --prefix desktop-tauri/mobile run build 并提交生成的产物，可同步这三处；构建成功后也可消除对应的产物同源差异。
