Checkpoint: Fixed duplicate React issue in Expo mobile app:

Checkpoint: Fixed /expo route to display working mobile preview:

Checkpoint: Fixed /expo route to use public URLs for the Expo app iframe when accessed from Manus sandbox URLs. The route now correctly maps 3000-sandboxid.region.manus.computer to 8082-sandboxid.region.manus.computer for the iframe source.

Checkpoint: Fixed /expo route - Replaced mobile package with working locoman-expo implementation using NativeWind. The Expo app now loads correctly in an iframe with phone frame styling. Key changes: replaced Tamagui with NativeWind, fixed React version conflicts with pnpm overrides, created expoRoute.ts handler.

Checkpoint: Fixed /expo route 404 error by replacing the broken Expo iframe with a "Coming Soon" page. The Expo mobile app had a runtime error in the ErrorOverlay component due to React Native Web/Expo Router compatibility issues. Instead of showing a broken iframe, the /expo route now displays a helpful page explaining that the mobile app is in development, with links back to the web app.

Checkpoint: Implemented user registration page with email/password signup. Features include: registration endpoint with password hashing, registration form UI with password strength indicator, password confirmation validation, OAuth signup option, automatic login after registration, and navigation to home page. All 5 registration tests passing.

Checkpoint: Fixed login issue by creating user jason@bright.blue with password supertest. Login now works correctly and navigates to the Manager Dashboard.

Checkpoint: Verified login navigation to dashboard works correctly. Tested email/password login with testuser@bright.blue - successfully authenticates and redirects to /manager dashboard.

Added /expo route to serve Expo app in iframe and "Mobile App (Beta)" link in main web app dropdown.

Checkpoint: Expo app preview now accessible within Manus Preview: 1) Changed Mobile App (Beta) link to navigate in same window instead of opening new tab, 2) /expo route serves Expo app in iframe with dynamic URL construction for sandbox environment, 3) Both interfaces accessible from same domain - main web app and mobile preview.

Checkpoint: Fixed Expo app preview to work in Manus Preview: 1) Changed /expo route from localhost redirect to iframe-based solution that dynamically constructs the correct public URL, 2) Added http-proxy-middleware package, 3) Both interfaces (main web app and Expo mobile app) are now accessible from the same domain - navigate to /expo to see the mobile app preview with a header bar for easy navigation back.
