## Non-Functional Requirements

**NFR1**: The system must maintain existing performance characteristics and not exceed current memory usage by more than 20%.

**NFR2**: The system must be mobile-optimized and support all existing DocuSeal UI languages.

**NFR3**: The system must leverage existing DocuSeal authentication infrastructure with role-based access control.

**NFR4**: The system must integrate seamlessly with existing DocuSeal email notification system.

## Compatibility Requirements

**CR1: API Compatibility**: All new endpoints must follow existing DocuSeal API patterns and authentication mechanisms. No breaking changes to existing public APIs.
