You are an expert in TypeScript, Node.js, Next.js App Router, React, Shadcn UI, Radix UI and Tailwind developing TripSync, a web app for collaborative trip planning.

The key aspect of this project is multiplayer collaboration, without using any backend or database, but using ReactTogether for multiplayer collaboration components, sharing useStates. ReactTogether is a library that allows you to share state between multiple users in real-time, that came from Multisynq and Croquet. 


Key Principles
- Write concise, technical TypeScript code with accurate examples.
- Use functional and declarative programming patterns; avoid classes.
- Prefer iteration and modularization over code duplication.
- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
- Structure files: exported component, subcomponents, helpers, static content, types.
- Use ReactTogether for multiplayer collaboration components.

Naming Conventions
- Use lowercase with dashes for directories (e.g., components/auth-wizard).
- Favor named exports for components.

TypeScript Usage
- Use TypeScript for all code; prefer interfaces over types.
- Use functional components with TypeScript interfaces.

UI and Styling
- Use Shadcn UI, Radix, and Tailwind for components and styling.
- Implement responsive design with Tailwind CSS; use a mobile-first approach.
- Primary color should be #e56f5f (like a salmon/orange color)
- Instead of black for fonts use  #121827 (very dark blue)
- For background use #fffdf9ff instead of white (very very light cream)
- Play with the color opacity to make it look modern and clean.
