Resolve 15 shared-control, overlay and responsive-layout issues plus the MCP editor being hidden behind settings. Restore theme contrast, danger and disabled states, visible keyboard focus, and consistent Continue fields. Keep the workbar add button reachable and model protocol values readable in narrow containers.
Make nested MCP and image dialogs usable above their parents with focus restoration, keep project Escape handling within the active modal, release native browser views for overlapping help, and restore keyboard access and Escape in sandboxed HTML previews without relaxing sandbox permissions. Add unit and real Electron regression coverage and update design and validation documentation.
Release note: 修复深浅主题下控件边框、危险操作、禁用状态和键盘焦点显示不一致的问题。MCP 编辑器与图片预览可在父弹窗上正常操作，HTML 全屏预览支持键盘进入和 Escape 返回；窄工作栏的添加按钮保持可用，模型连接协议文字完整可读。
Validation: the full suite recorded 5309 passed, 3 failed and 83 skipped. The ProjectSwitcher initial-focus regression was then fixed, and App, ProjectSwitcher and overlay Electron tests passed all 331 cases. The other two HeartbeatCenter failures were reproduced on isolated HEAD 11facf0 and remain pre-existing. Typecheck and lint passed after the fix; staged whitespace checks passed. The full suite was not rerun after the focused fix.
Limits: Electron evidence is from Windows development runs, with fixtures for unrelated services and native occlusion throttling disabled in some drivers. No production build, packaging, macOS/Linux, remote Agent host or external MCP connection validation; skipped tests and the documented scaling and native-select coverage gaps remain.
会话 HTML 渲染
会话 HTML 渲染让用户直接查看 Agent 回复中的网页结果，而不必先复制代码到外部文件。 该能力默认开启，也可以在“设置 > 平台功能 > 通用设置”中关闭。
功能边界
- 只渲染已完成的 Agent 正文和已完成的子 Agent 输出。
- 支持完整 HTML 文档、单一 HTML 根元素，以及 Markdown 中的
html/htm代码块。 - 使用无脚本、无网络、无表单提交和无窗口操作权限的静态隔离预览。
- 每个预览提供源码切换和全屏预览两个图标操作；全屏预览沿用同一清理和隔离边界。
- 用户消息、推理过程和流式中的回复不执行 HTML；关闭功能后继续显示 HTML 源码。
- 本功能不把普通聊天回复复制为成果，也不替代助手工作栏中独立成果的预览流程。
文档
术语
- HTML 源码：Agent 回复中原始、可复制的 HTML 文本。
- 静态预览：在隔离
iframe中显示的 HTML；脚本、联网和外部操作均被禁用。 - 全屏预览：在应用级 Modal 中显示同一份静态预览文档，用于查看完整页面布局。
