这三个提供的文件足以构成本地 Web 示例。JSX 包含提供程序、一份配置、生成的主题 CSS 和完整看板。build.mjs 固定了 Web 目标和生产环境，并为其他仅限浏览器的环境读取提供空的 process.env 回退值。缺少最后这项定义时，即使代码可以编译，这个纯浏览器打包也可能因 process is not defined 而失败。
将 tamagui.jsx、build.mjs 和 index.html 保存在同一目录中。
安装固定版本的 React 和 Tamagui 包。
构建并提供本地目录。
测试空内容和重复项的添加、完成状态、筛选、主题与重置。
将原生端与 Web 端的采用方式分开
