Default variant on PDP load?

[zamson]

I'm selling products in my store with multiple sizes (S, M, L, etc.). The smallest size (S) is often out of stock. How can I set the default size to "M" without rearranging the options?

What's the best way to do this? 🙇🏽‍♂️

Update the logic here to pick a default variant. By default it just picks the "first variant": https://github.com/Shopify/hydrogen/blob/main/templates/skeleton/app/routes/products.%24handle.tsx#L57
