OVERVIEW

Implementation Approach

• Phase 3: Build Site Builder with wizard, AI structure generation, and file management
• Phase 4: Implement Linker and Optimizer as post-processing stages with multiple entry points
• Shared Components: Create global component library for reuse across apps
• Integration: Ensure seamless integration with existing Phase 1 & 2 services

Key Principles

• Service Layer Pattern: All business logic in services (Phase 1 pattern)
• Credit-Aware: All operations check credits before execution
• Multiple Entry Points: Optimizer works from Writer, WordPress sync, 3rd party, manual
• Component Reuse: Shared components across Site Builder, Sites Renderer, Main App
