- Added client mount state to the dashboard to prevent premature interactions before the component is fully loaded. - Updated button disabling logic to ensure it reflects the component's readiness and user session state. - Introduced zIndex handling in canvas placement context for better node layering. - Enhanced asset and image nodes with improved resizing logic to maintain aspect ratios during adjustments. - Refactored node components to streamline rendering and improve performance during dynamic updates.
