I went down a bit of a rabbit hole on this one as it gets a bit tricky when factoring in safe areas and portrait/landscape orientations. I ended up with the following code that accounts for most of the requirements that we need to follow:

/** * Card style modal needs additional padding on the  * top of the header. We accomplish this by targeting * the first toolbar in the header. * Footer also needs this. We do not adjust the bottom * padding though because of the safe area. */html.iosion-modal.modal-cardion-headerion-toolbar:first-of-type,html.iosion-modalion-footerion-toolbar:first-of-type {
padding-top:6px;
}
/** * Card style modal needs additional padding on the  * bottom of the header. We accomplish this by targeting * the last toolbar in the header. */html.iosion-modal.modal-cardion-headerion-toolbar:last-of-type {
padding-bottom:6px;
}
/** * Add padding on the left and right * of toolbars while accounting for * safe area values when in landscape. */html.iosion-modalion-toolbar {
padding-right:calc(var(--ion-safe-area-right) +8px);
padding-left:calc(var(--ion-safe-area-left) +8px);
}

Let's place this in the core.scss file, and then we should be good to merge.
