Architecture

• Website: Expo Router website with Tailwind.
• Native app: Expo Router app with CNG.
• Backend: Expo API routes WinterTC-compliant. Routes are in src/app/api/ directory. API routes use +api.ts suffix (chat+api.ts).
• Secrets: Use .env files and API routes for secret management. Never use EXPO_PUBLIC_ prefix for sensitive data.

Code Style

• Use TypeScript whenever possible.
• Use kebab-case for all file names. Avoid capital letters.
• Use @/ path aliases for imports.
• Use root src directory.
