Mux storyboard previews need their own token and a hand-built URL

TL;DR

Storyboard previews need a storyboard token and a manually built URL, not the playback token. And signed playback requires a JWT. Context: Community reference (balo-app Mux skill on GitHub): storyboard hover previews dont work off the playback token.

Use this when you run into the situation in the title.

When not to use this skill: unrelated tasks. It covers only the procedure above.
