You are a solutions architect. Create a clean, high-level system architecture diagram for an AI-powered hackathon review platform.                                  The system has two paths:                                                                                                          READ PATH (instant): A judge clicks View Detail, hits FastAPI with Cognito auth, queries DynamoDB, returns rendered HTML.                                 WRITE PATH (async): An admin clicks Run Review, hits FastAPI with Cognito auth, creates a job in DynamoDB, enqueues to SQS, picked up by Lambda running a Strands Agent which fans out to 5 parallel judge agents, fans back in to a synthesis step, stores results back to DynamoDB. Seven layers top to bottom:    1. Presentation - Browser for Judge and Admin   2. Application - FastAPI with AWS Cognito                                                                                 3. Data - AWS DynamoDB                     4. Messaging - AWS SQS as the decoupling boundary between sync and async   5. Processing - AWS Lambda with Bedrock AgentCore and Strands Agent running 5 parallel judges that fan into synthesis   6. AI/LLM - AWS Bedrock using Claude Sonnet 4.5    7. External - GitHub API                                                                                                                                 Diagram requirements:   - Show both read and write paths clearly                                 - Show the fan-out and fan-in of the 5 judges   - Service names only, no table names, field names, or internal details   - Keep it minimal, one box per service, labels on arrows only where needed
