Neat! I think it could benefit from a toggle to make it a static transcript, without the interactivity, so people can read it without the timecodes or button semantics while using a screen reader or any text-to-speech tech.
The toggle control could do something like add/remove a 'static' class on the custom element and make the click handler inactive.
```CSS
youtube-deep-link.static [data-offset] button {
display: none;
}
```
