Next Steps (For Manual Testing)

Start the backend API (port 3000)
Start gograb-space (port 5200)
Navigate to /s/{space-slug}/modularity to test:
- Create new module with widgets
- Attach flows to module
- Save to backend
Navigate to /s/{space-slug}/modular-universe to test:
- View created modules
- Drag-drop modules to canvas
- Test widget rendering with flows
