   * 2. Replace the `provider` / `providerOptions` keys below with:

   *      providerOptions: {
   *        baseUrl: env('CDN_URL'),           // optional CloudFront/CDN origin

   *        },
   *      },
   *      actionOptions: { upload: {}, uploadStream: {}, delete: {} },

   * 3. Add the bucket/CDN host to the Content Security Policy in
   *    `config/middlewares.ts` (`img-src` and `media-src`), otherwise the admin
   *    panel shows broken thumbnails.
   * 4. Set the AWS_* / CDN_URL variables listed in `.env.example`.
