5. Security Considerations

5.1 Authentication

• Firebase Authentication with email/password
• Secure token management with Firebase SDK
• Role-based access control for administrative functions
• Client persistence with firebase.auth.Auth.Persistence.LOCAL

5.2 Data Protection

• Form data processing occurs client-side for privacy
• Secure API endpoints with server-side validation
• Input validation and sanitization before processing
• Firebase security rules to enforce data access control

6. Performance Optimization

6.1 Frontend

• CSS optimizations with critical styles loaded first
• Deferred script loading for non-critical resources
• Efficient state management with vanilla JavaScript
• Dynamic loading of form components

6.2 Backend

• Efficient PDF processing with client-side generation
• Static asset delivery for core form templates
• Optimized Firebase queries with specific document references
• Request batching for related data operations

7. Current Implementation Details

7.1 Form Selection Implementation

• Province selection from predefined array of 10 Canadian provinces
• Dynamic loading of categories based on issuesStructure[province] data
• Selection summary breadcrumb navigation for easy hierarchy traversal
• Tag-based categorization for direct forms and regular categories

7.2 Form Generation Implementation

• HTML forms with client-side validation for data collection
• PDFLib.js for client-side PDF generation without server roundtrip
• Coordinate-based text placement system for precise form filling
• Base64 encoding of generated PDFs for direct browser display

7.3 Subscription Implementation

• Firebase Firestore database for subscription storage
• Document structure with users/{email}/subscriptions/{formId} pattern
• Subscription checking via SubscriptionCheck class
• Multiple subscription tiers with different access levels
