 这些 JSON 是早期演示数据，当前导览模块不再以这里作为数据源。

-当前室内导览、设施搜索、位置预览统一通过 Provider / Adapter / Repository / UseCase 数据边界读取 `static/nav-assets/codex_nav_20260621_175310_museum_default_centerline_finalxy`，页面和展示组件不要直接依赖静态包 JSON 文件。
+当前馆内导览、设施搜索、位置预览统一通过 Provider / Adapter / Repository / UseCase 数据边界读取 `static/nav-assets/codex_nav_20260621_175310_museum_default_centerline_finalxy`，页面和展示组件不要直接依赖静态包 JSON 文件。

 当前展厅、单元、讲解点、展品、讲解词和 POI 业务内容统一通过 `static/guide-data` 静态数据包读取，默认数据源模式为 `VITE_GUIDE_CONTENT_SOURCE_MODE=static`。
