Gotchas

• Video ID only — pass dQw4w9WgXcQ, not a URL. Strip https://www.youtube.com/watch?v= and any &t= or &list= params.
• Transcript may not exist — auto-generated captions exist for most popular videos but not all. A 404 means no captions for that language.
• JSON is default — fmt=text gives plain newline-separated lines, fmt=srt gives SRT subtitles with timestamps. No fmt flag gives JSON with text, start, duration fields.
• Timestamps are seconds — start and duration in JSON are float seconds, not milliseconds.
