When using Shopify for products with multiple variations (variants), you may not necessarily want to display the default size or color first. This is an example of how to set the variant to be displayed when transitioning from the product listing page in the "Dawn/Rise" theme.
Example of settings that allow you to specify the first variant displayed on collection and product detail pages in the themes "Dawn" and "Rise".
[Method 1] Create a single product metafield with the "product variation" format named "custom.initial_variant"
[(For the Rise theme) Setup step 2] Add the code to "snippets/card-product.liquid" and replace `card_product.featured_media` with another variable.
[(For the Rise theme) Setup step 3] Add code to the href attribute value of multiple product links (A tags) in "snippets/card-product.liquid"
