Avenue Shop - Larger Text for Product List + Prices

Site URL: https://raspberry-cow-26ht.squarespace.com/config/design/styles

Hello, hello! I'd like the product titles & price to be a bit larger and I can't figure this one out. I haven't found anything in the site styles and these suggestions I found for similar scenarios didn't work: 

.ProductList .ProductList-title {
	font-size: 30px;
}

<style>
  .product-title {
    font-size: 4rem !important;
}
</style>

/* Product Block Titles */
.product-block .productDetails .product-title {
  font-size: 1.8em;
}
/* Product Block Prices */
.product-block .productDetails .product-price {
  font-size: 1.5em;
}

Any suggestions? My shop isn't visible because I haven't launched it yet, so I included a couple screenshots. 

Thank you so much! 🙂
