Global (WebRTC)
• End-to-end encrypted, password-protected peer-to-peer stream
• Shares screen, microphone, and device audio where supported
• Viewers join with Stream ID + password in any WebRTC-enabled browser
• Requires Internet; signaling handled by public open source server
• Audio/video flows directly between devices - bandwidth grows per viewer
