+## Technology stack
+
+AI ThemeStore Community is a hybrid native macOS app: **Swift and SwiftUI**
+provide the application interface, while a local **JavaScript and CSS theme
+engine** handles Codex theming, verification, and recovery.
+
+| Layer | Technology | Responsibility |
+| --- | --- | --- |
+| Native app | Swift, SwiftUI | Theme library, controls, status, and user-facing recovery |
+| Theme engine | JavaScript (ESM), CSS | Apply themes and verify New Chat and active task surfaces |
+| Lifecycle tools | POSIX shell | Start, pause, restore, diagnose, and build the app |
+| Build system | Swift Package Manager | Compile and package the native macOS application |
+
+GitHub's language label is based on source-code byte count, so it may show
+JavaScript even though the user-facing application is native SwiftUI.

+## 技术栈
+
+AI ThemeStore Community 是一套混合架构的原生 macOS App：**Swift 与
+SwiftUI** 提供应用界面，本地 **JavaScript 与 CSS 主题引擎**负责 Codex
+主题应用、验证和恢复。
+
+| 层级 | 技术 | 职责 |
+| --- | --- | --- |
+| 原生 App | Swift、SwiftUI | 主题库、控制界面、状态展示和用户侧恢复 |
+| 主题引擎 | JavaScript（ESM）、CSS | 应用主题并验证 New Chat 与运行中任务界面 |
+| 生命周期工具 | POSIX shell | 启动、暂停、恢复、诊断和构建 App |
+| 构建系统 | Swift Package Manager | 编译和打包原生 macOS 应用 |
+
+GitHub 的语言标签依据源码字节数计算，因此即使用户看到的是原生 SwiftUI App，
+仓库仍可能显示 JavaScript。

 ## 适配 Codex 的实践经验
 
 Codex 是持续演进的产品，因此稳定主题不能只是一张壁纸，也不能依赖一组脆弱的
