    // - For Vite, the actual compilation target is determined by the
    //   `build.target` option in the Vite config.
    //   So don't change the `target` field here. It has to be
    //   at least `ES2020` for dynamic `import()`s and `import.meta` to work correctly.
    // - If you are not using Vite, feel free to override the `target` field.
