*
* **Supported Content Types:**
* - Images: image/png, image/jpeg, image/gif, image/webp, image/svg+xml
* - Documents: application/pdf, text/plain, text/markdown, text/html
* - Code: text/javascript, application/json, text/css, text/yaml
* - Archives: application/zip, application/gzip
* - Video: video/mp4, video/webm (use presigned URL for large files)
*
