Is it possible to change the font of the cart that displays how many items & change font on checkout page

Site URL: https://www.russellbrxwn.com/merch

I was trying to change the font on both of these but have hit a dead end. I'm trying to change the font where it displays 1 item and the dollar amount to the same as the rest of my site and I'm trying to change the default text as well on the checkout screen. Any help? Thanks

You can't change on /checkout page. SS has blocked this.

with cart, add to Home > Design > Custom CSS

.sqs-pill-shopping-cart .details * {
    color: red;
    font-size: 20px;
    font-family: monospace !important;
}
.sqs-pill-shopping-cart .subtotal .price {
    font-size: 30px;
    font-family: futura-pt !important;
    color: green;
}
