● Read(src\app\dashboard\[userId]\brand-modules-library\components\LibraryPageLayout.tsx)
  ⎿  Read 32 lines (ctrl+r to expand)

● Update Todos
  ⎿  ☒ Analyze existing codebase structure and database schema
     ☒ Implement API route for user's section packs
     ☒ Create library page main component and layout
     ☐ Implement data fetching hooks (useLibraryData)
     ☐ Implement library actions hook (install functionality)
     ☐ Connect to Theme Enhancer for pack installation
     ☐ Create library UI components (Header, Grid, EmptyState)
     ☐ Implement filtering and search functionality
     ☐ Create pack detail modal and install panel
     ☐ Test the complete flow and fix any issues

● Now let me update the useLibraryData hook to use the correct API endpoint:
