How this replaces Streamlabs
1Fit zone — yellow frame is the picture; pick Full / Safe / Phone / Square / Lower.
2Studio scenes — Starting Soon, Duel, Cam, BRB (works on iPhone).
2Program preview — what Twitch sees, with title + LIVE + alerts.
3Go Live — canvas + mic → our encoder → Twitch (no third-party app for these scenes).
4Desktop Screen scene — Fortnite / GFN when browser allows capture.
External games on pure iPhone still need Streamlabs for full-screen app capture — iOS blocks that in every browser. Studio covers card games, chat, and show screens natively.
