[ajmaluk]

Design and implement user interfaces for group trip planning:

• Trip creation screen: Add trip details, invite travelers, specify preferences
• Group management screen: View group members, itinerary, chat/invite others
• Itinerary editor: Allow participants to collaboratively modify plans

Please specify:
• Preferred UI elements and user flows
• Accessibility or design system constraints
• Any mockups/screenshots that would guide UI
