User Personas

• Admin logs in -> manages user accounts -> updates content -> monitors system performance.

Visuals Colors and Theme

• primary: #1A73E8 (a deep blue for brand identity)
• primary_light: #E8F0FE (a light blue for hover states)
• secondary: #FF7043 (a coral hue for emphasis)
• accent: #FFD700 (a vibrant gold for CTAs and active states)
• highlight: #FFA726 (a warm orange for notifications)
• bg: #FFFFFF (a clean white background)
• surface: rgba(255, 255, 255, 0.8) (a translucent white for cards/panels)

Signature Design Concept

The homepage of VoyageAI will feature an interactive 3D globe that users can rotate and zoom into to explore destinations. Each destination will be marked with a glowing pin, and clicking on a pin will open a detailed card with information and images. This concept will be implemented using @react-three/fiber for 3D rendering and gsap for smooth animations and transitions. The globe will provide an engaging and immersive experience, making the exploration of destinations both fun and informative.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, providing a layered depth effect as users scroll through the page. Decorative elements will move at different speeds to create a dynamic visual experience, while content remains in the natural flow. Internal pages will adopt a "static" model for clarity and ease of use, focusing on data-heavy interactions like itinerary management and expense tracking.

Non-Functional Requirements

• The application must be responsive and function seamlessly on desktop, tablet, and mobile devices.
• It should maintain high performance with fast load times and smooth transitions.
• The system should be secure, ensuring user data privacy and protection.
• The application should be scalable to accommodate a growing user base and feature set.

Tech Stack

• Database: MySQL or MariaDB, using Alembic for migrations
• AI Models: GPT 5.4 for user-friendly responses
• AI Tools: Litellm for LLM Routing, Langchain
• Local Orchestration: Docker, docker-compose
