# Spectator & Cast Mode

Two views for two audiences: spectators who watch, and casters who commentate.

## Spectator Mode

The spectator view (`/spectate/[lobby-id]`) is the audience experience. Share this URL with viewers.

**What spectators can do:**

* Watch live trading action with real-time price updates
* See the leaderboard update as traders make moves
* Chat with other spectators
* Vote on predictions (who will win, which direction the market goes)
* Trigger sabotage events against traders using their own credits

Spectators are part of the game. Their sabotage attacks can change the outcome of a battle.

## Cast Mode

The cast view (`/cast/[lobby-id]`) is built for commentators and streamers. It shows everything spectators see, plus:

* Detailed trader stats and position breakdowns
* Additional controls for camera focus (highlight specific traders)
* Historical data for context during commentary
* Event timeline showing what happened and when

## Best practices

* **For online streams:** Share the spectator link in your stream description. Viewers can interact from their own device while watching you commentate.
* **For IRL events:** Put the stage view on the big screen, give casters the cast view on their monitors, and let the audience use spectator mode on their phones.
* **For tournament brackets:** Use multiple lobbies and switch between broadcast views as matches progress.
