cellVisibilityLogic
Optional per-cell conditional logic that controls whether an individual cell is visible.
Parsed from the cellVisibilityLogic JSON property and evaluated per-row. Like cellRequiredLogic, its conditions may mix same-row {column:...} references and document {file,page,field:...} references. Conditions met + show action -> visible; met + hide -> hidden; not met -> falls back to cellsHidden.
