      final icon = node.customData?['icon'] as String? ?? '📋';
      final priority = node.customData?['priority'] as String? ?? 'medium';
      
      return GestureDetector(
        onTap: onTap,
        child: Container(
          decoration: BoxDecoration(
            color: node.color,
            borderRadius: BorderRadius.circular(16),
            border: Border.all(color: _getPriorityColor(priority), width: 3),
          ),
          child: SingleChildScrollView(
            child: Padding(
              padding: EdgeInsets.all(8.0),
              child: Column(
                children: [
                  Text(icon, style: TextStyle(fontSize: 14)),
                  Text(node.title, style: TextStyle(fontSize: 11)),
