-Settings ownerless-copy plugin: registers everything on the Settings surface that belongs to no single feature — the shell's trigger/header/close chrome content, the General section and its `settings.general.item` slot, and the `settings` dictionaries. Feature-owned rows (Permission, Language, Appearance) and sections (Models) stay with their feature packages.
+Settings ownerless-copy and product-onboarding plugin: registers everything on the Settings surface that belongs to no single feature — the shell's trigger/header/close chrome content, the General section and its `settings.general.item` slot, the `settings` dictionaries, and the first ordered welcome step. Feature-owned rows (Permission, Language, Appearance), sections (Models), and conditional onboarding steps stay with their feature packages.
+
+`src/onboarding-copy.ts` is the single editable owner of the complete Chinese and English notice plus `WELCOME_NOTICE_VERSION`. The Host half registers `ui-onboarding` in the user-settings seam; the browser compares `welcomeNoticeVersion` for exact equality and writes the current value only after Continue succeeds. The path mutation is idempotent across tabs and preserves sibling settings, while `host/settings-changed` makes an externally acknowledged notice advance without a reload. A different version deliberately presents the notice again. The welcome page preserves every authored paragraph, gives the requested clause in the final paragraph the sole emphasis, initially focuses the title, and has no close, Escape, mask-click, or secondary path. None of its copy or acknowledgement enters a Session log or model request.

+
+`src/onboarding-copy.ts` 是完整中英文通知文案和 `WELCOME_NOTICE_VERSION` 的唯一可编辑来源。宿主端在 user-settings seam 中注册 `ui-onboarding`；浏览器比较 `welcomeNoticeVersion` 是否精确相等，仅在「继续」操作成功后写入当前值。该路径变更在不同标签页间幂等，并会保留同级设置；`host/settings-changed` 则让页面在通知被外部确认后，无需重新加载即可推进。版本不同时，系统会有意重新显示通知。欢迎页保留原文的每个段落，仅强调最后一段中指定的句段，初始焦点落在标题上，并且没有关闭操作、Escape、点击遮罩或次要操作路径。其文案和确认状态均不会进入会话日志或模型请求。
