Coverage for src/lilbee/cli/tui/widgets/notice_dialog.py: 100%

1"""A minimal single-dismiss modal for an informational notice. 

2 

3Unlike :class:`ConfirmDialog` there is nothing to decide: the modal states one 

4thing and closes. Used when a feature is turned off and its view is opened, so 

5the user learns why nothing happened rather than facing a dead screen.
