[FIGURE_02]PROJECT_HUB_ARCHITECTURE

Project Hub is a multi-tenant monorepo architecture. The Next.js client renders high-density telemetry dashboards connected via cookies to an Express gateway. The API enforces Redis Token Bucket rate limiting and cryptographic invite validation before committing transactions to PostgreSQL database and Redis cache layers.
