## Features

- **Nashville Numbers & transpose**: Key in chord progressions as Nashville numbers or chord letters and toggle between them instantly. Transposing a song is just changing its key — every chart follows. Lyrics can be shown or hidden with one tap.
- **Multiplayer chord sheets**: Google Docs for chord sheets. Everyone opens the same document and sees edits in realtime. Share a link, no download needed. Edits made offline sync when you reconnect.
- **Arrangements**: Mark up intros, verses, choruses and instrumental sections with colour coding so nobody gets lost mid-song.
- **Built-in metronome**: Every song stores its tempo, so the click is ready before you count in. No hunting for BPMs one song at a time.
- **Drone pad**: A drone pad for transitions, which crossfades between keys as you move from song to song — useful when there is no second keys player.

## Notes

- Public pages content-negotiate markdown: send `Accept: text/markdown` and
  the same URL returns `text/markdown; charset=utf-8`.
- Paths that do not exist return HTTP 404 with a markdown body listing these
  same entry points.
- Everything under `https://setlist.moosedev.app/setlist` requires a signed-in account
  and holds user-owned setlists, so there is nothing there to crawl.
