     * :::warning Strict URL and folder structure requirements
     * The `appUri` **must** follow the exact folder structure produced by the signageOS Device-app Builder.
     * The upgrade will fail silently (device reverts to the previous version) if the URL does not match the expected format.
     *
     * Key rules:
     * 1. **The folder structure on your server must match the ZIP package from signageOS exactly.** Do not rename files or reorganize folders.
     * 2. **HTTP redirects (e.g., 302) are not supported.** Files must be directly accessible at the expected URLs.
     * 3. **The URL must not end with a trailing slash (`/`).** A trailing slash causes the upgrade to fail.

     * The expected URL format differs per platform:
     *
     * | Platform | URL format |
     * |----------|-----------|
     * | **Tizen** | Point to the **folder** containing `sssp_config.xml` and `*.wgt` — not to a specific file. E.g. `https://cdn.example.com/app/tizen/2.10.1/landscape` |
     * | **SSSP** | Point to the **folder** containing `sssp_config.xml` and `*.wgt`. E.g. `https://cdn.example.com/app/sssp/2.10.1/landscape_full-hd` |
     * | **webOS 1, 2** | Point to the **ZIP file** directly. E.g. `https://cdn.example.com/app/webos/2.10.1/ApplicationName.zip` |
     * | **webOS 3+** | Point to the **IPK file** directly. E.g. `https://cdn.example.com/app/webos/2.10.1/ApplicationName.ipk` |
     * | **BrightSign** | Point to the **zip file** directly. E.g. `https://cdn.example.com/app/brightsign/2.10.1/display-brightsign.zip` |
     * | **Android** | Point to the **APK file** directly. E.g. `https://cdn.example.com/app/android/2.10.1/io.signageos.android.apk` |
     * | **Windows** | Point to the **zip file** directly. E.g. `https://cdn.example.com/app/windows/2.10.1/windows_2.10.1.zip` |
     * | **ChromeOS** | Not supported |
