The main screen consists of:

• Tab bar at the top
• Tab content area
• Status bar at the bottom

Available Tabs

• Chat: User list and message history with infinite scrolling
• Admin: Administrative functions
• Status: Connection and system status
• Help: Keyboard shortcuts and help

Message Display

Messages are rendered with:

• Date separators (“Today”, “Yesterday”, or formatted dates)
• Timestamps in 12-hour format (HH:MM AM/PM)
