WHY IT NEEDS A POLICY

Why design_slide needs a policy

This tool creates or substantially modifies slide design properties (layout, typography, color) within a presentation. While it performs structured presentation authoring rather than arbitrary execution, it irreversibly alters presentation state in ways that require user intervention to undo.
