## Overview

This is a Telegram Web user script that restores media-download controls for restricted chats, channels, and stories. Users open media in Telegram and use the added controls to download images, GIFs, videos, and (on supported WebK versions) audio. The implementation is a single source file; the excerpts show download and progress mechanics, but omit some event wiring, so uncertain internal dispatch links are not shown.

Main entry points: [`src/tel_download.js`](https://github.com/neet-nestor/telegram-media-downloader/blob/main/src/tel_download.js) (Download controls)
