## Summary by CodeRabbit

* **Style**
* Adjusted the empty-state illustration layout by removing explicit
height constraint classes from the wrapper elements. The component's
vertical sizing is now managed through alternative approaches while
preserving existing positioning, scale transformations, and
pointer-event configurations. These refinements maintain visual
consistency while improving the overall layout behavior for the empty
state display.
