 KEY FEATURES
═══════════════════════════════════════════════════════════════════

✅ Dynamic Provider Discovery
   • Fetches providers from OBP API /obp/v5.1.0/well-known
   • No hardcoded provider list
   • Automatic provider registration

✅ Multi-Provider Support
   • OBP-OIDC, Keycloak, Google, GitHub
   • Strategy pattern for extensibility
   • Environment variable configuration

✅ Health Monitoring
   • Real-time provider status tracking
   • 60-second health check intervals
   • Automatic status updates

✅ Security
   • PKCE (Proof Key for Code Exchange)
   • State validation (CSRF protection)
   • Secure token storage

✅ User Experience
   • Provider selection dialog
   • Single provider auto-login
   • Provider icons and formatted names
   • Loading states and error handling

✅ Backward Compatible
   • Legacy single-provider mode still works
   • No breaking changes
   • Gradual migration path

 API ENDPOINTS
═══════════════════════════════════════════════════════════════════

NEW:
  GET /api/oauth2/providers
    Returns: List of available providers with status

UPDATED:
  GET /api/oauth2/connect?provider=<name>&redirect=<url>
    Initiates login with selected provider

  GET /api/oauth2/callback?code=<code>&state=<state>
    Handles OAuth callback from any provider

═══════════════════════════════════════════════════════════════════
 CONFIGURATION
═══════════════════════════════════════════════════════════════════

Environment Variables (per provider):

# OBP-OIDC
VITE_OBP_OAUTH2_CLIENT_ID=your-client-id
VITE_OBP_OAUTH2_CLIENT_SECRET=your-secret
VITE_OBP_OAUTH2_REDIRECT_URL=http://localhost:5173/api/oauth2/callback

# Keycloak
VITE_KEYCLOAK_CLIENT_ID=your-client-id
VITE_KEYCLOAK_CLIENT_SECRET=your-secret
VITE_KEYCLOAK_REDIRECT_URL=http://localhost:5173/api/oauth2/callback

# Add more providers as needed...

═══════════════════════════════════════════════════════════════════
 TESTING
═══════════════════════════════════════════════════════════════════

See: MULTI-OIDC-TESTING-GUIDE.md

15 comprehensive test scenarios covering:
  ✓ Provider discovery
  ✓ Backend API endpoints
  ✓ Login flows (single/multiple providers)
  ✓ Health monitoring
  ✓ Session persistence
  ✓ Error handling
  ✓ Security (PKCE, state validation)
  ✓ Backward compatibility

 NEXT STEPS
═══════════════════════════════════════════════════════════════════

1. Test the Implementation
   └─ Follow MULTI-OIDC-TESTING-GUIDE.md

2. Configure Environment
   └─ Set up provider credentials

3. Start Services
   ├─ Start OBP API
   ├─ Start OIDC providers (OBP-OIDC, Keycloak)
   ├─ Start backend: npm run dev:backend
   └─ Start frontend: npm run dev

4. Test Login Flow
   ├─ Navigate to http://localhost:5173
   ├─ Click "Login"
   ├─ Select provider
   └─ Authenticate

5. Create Pull Request
   └─ Merge multi-login → develop
