-### Tearsheet group (infinite stacking)
+Limit stacked tearsheets to a maximum of three.
+Flows requiring four or more levels should be redesigned using multi-step wizard or dedicates page to prevent loss of user context.
 
-Use a `TearsheetGroup` to manage an unbounded number of stacked tearsheets.
-`children` rendering order determines stacking priority with later children stacking in front of earlier ones.
-Only the top 3 open tearsheets are visible; earlier ones hide behind the stack and reappear as front tearsheets are closed.
