- Add 'total' prop to VirtualList for accurate scrollbar height in pagination scenarios
- Add 'onNearBottom' callback to trigger auto-loading when user scrolls near end
- Update FontVirtualList to forward the new props
- Implement auto-pagination in SuggestedFonts component (remove manual Load More button)
- Display loading indicator when fetching next batch
- Show accurate font count (e.g., "Showing 150 of 1920 fonts")
Key changes:
- VirtualList now uses total count for height calculation instead of items.length
- Auto-fetches next page when user scrolls within 5 items of the end
- Only fetches if hasMore is true and not already fetching
- Backward compatible: total defaults to items.length when not provided
- Use path aliases instead of relative paths
- Fixes module resolution errors when importing from other files
- Ensures fallback to Fontshare API works correctly
- Add gcTime parameter to TanStack Query config
- Add response validation in fetchFn with detailed logging
- Add fallback to Fontshare API when proxy fails
- Add USE_PROXY_API flag for easy switching
- Fix FontVirtualList generic type constraint
- Simplify font registration logic
- Add comprehensive console logging for debugging
Fixes: Query data cannot be undefined error
