Subject: [PATCH] style: update Kanban components for improved background
 effects - Adjusted background opacity in `Board` and `SwimlanesBase`
 components to enhance visual layering. - Modified `Card` component to support
 a new `background` prop for better customization of column cards. - Updated
 styles for `Card` variants to include new gradient effects and backdrop blur
 adjustments, improving overall aesthetics.
