• zero user interaction

Characteristics

• No authentication UI
• No navigation
• No persistent client state
• Must survive reloads

Entry Points

• /overlay/spotify

Data Sources

• Chat Backend (WebSocket)
• Spotify integration (via backend or polling endpoint)

Non-Goals

• Input handling
• User configuration
• Auth flows
