Evaluates the number of nodes contained in each level of a workflow.

It allows you to define a minimum and maximum thresholds for node counts per level:
Minimum nodes per level: Prevents creating components or metanodes that contain only 1–2 nodes, which may indicate unnecessary nesting. The root level of the workflow is excluded from the minimum check, since small top-level workflows are valid.
Maximum nodes per level: Helps enforce readability and maintainability by flagging overly dense components or metanodes.

This check uses the Workflow Summary column, typically generated by the "Workflow Summary Extractor" node.
