+   - yt-dlp (auto-downloaded to .\bin if missing)
+   - ffmpeg (must be on PATH, or set -FfmpegDir)
+   - cookies.txt next to this script is used automatically if present
+.EXAMPLE
+  .\yt-download.ps1 "https://www.youtube.com/watch?v=xxxx"
+.EXAMPLE
+  .\yt-download.ps1 URL1 URL2 URL3 -OutDir "D:\Videos"
