- Fix axis mapping for nested frames with different layout directions (e.g. vertical child inside horizontal parent had swapped sizing) - Fix stretch alignment not applying to leaf children when set on parent - Fix layoutGrow being ignored on children with FIXED primaryAxisSizing - Add 42 unit tests covering all layout scenarios
