Next Steps

Based on the current implementation status, the recommended next steps are:

  1. Complete Task 2: Implement template factory and seeder system
  2. Continue Task 3: Build template service layer with core business logic
  3. Progress Task 4: Create template API controllers and routes
  4. Advance Task 5: Implement brand management system

This sequential approach ensures that each foundational layer is properly built before moving to the next, maintaining the architectural integrity and testability of the system.
