#   - Multi-model storage (relational, graph, vector, document)
#   - Secondary indexes
#   - Basic query engine (AQL)
#   - REST API (HTTP/1.1)
#   - GraphQL (basic)
#   - Basic time-series support
#
# Features NOT included:
#   - LLM integration
#   - GPU acceleration
#   - Horizontal sharding
#   - Replication
#   - Advanced protocols (HTTP/2, WebSocket, gRPC, MQTT, PostgreSQL Wire)
#   - Voice assistant
#   - Content processors
#   - OpenTelemetry tracing
#   - RBAC (basic auth only)
#   - Field-level encryption
