Locale plugin: LocaleRuntime — the `zh`/`en` preference stored as `locale.preference` in `$DSH_HOME/settings.yaml`; when that explicit Host value is absent, a fresh browser starts provisionally in the language `navigator` asks for (primary-subtag matching, with `en` when it asks for no language this app ships). The Host read runs after plugin activation so an unavailable settings service cannot block the page; its result replaces the provisional browser value live. Remote browsers retain only a process-local selection because the settings API is loopback-only. `locale/change` fires on switches, and the plugin points `<html lang>` at the active locale (`zh-CN`/`en`) on activation and on every switch. The service also owns the ns×locale dictionary registry (typed `register(ns, {zh, en})` checked against `LocaleNamespaceMap`, `bind(ns)`→`TranslateNS<ns>`; lookup chain ns → common → en → key), implements the slot system's `LocaleFace`, and installs itself through `ctx.slots.installLocale`, backing the framework-injected `t` standard seat (`Translate`/`TranslateNS` are ui-slots types; import them from there — this package only re-exports for dictionary owners' convenience). The [Host-backed preferences decision](../../../.agents/notes/implemented/bug-fix/2026-08-06-host-backed-web-preferences.md) owns the persistence boundary.
