  • EventCheckinPage.jsx - Check-in confirmation screen with event info
  • EventChatPage.jsx - Access control (verify participation before showing chat)
  • EventsPage.jsx - Check-in requirement notice, dev-only details link
• Security implementation:
  • Frontend access control (check participation status)
  • Socket.IO handler verification (prevent auto-participation)
  • Dev-only QR code access (import.meta.env.DEV)
  • Leave Event button with confirmation modal
• UX improvements:
  • Real participant counts using _count.participants
  • Joined events shown first in events list
  • Check-in required screen for non-participants
