+- **Command Repositories**: Handle write operations, work with full domain entities, enforce business rules
+- **Query Repositories**: Handle read operations, return optimized DTOs, support pagination and sorting
+- **Separation**: Commands use `I{Entity}Repository`, queries use `I{Entity}QueryRepository`
