UR: Hide Sold Out Variants

Shopify themes keep sold out options in the variant picker, so customers pick a size or color only to find it can't be bought. This app removes those options on product pages, based on the combination currently selected: choose Red and the sold out M disappears, switch to Blue and it comes back. Prefer to keep them visible? Dim them instead. Variants set to continue selling stay visible, and you can also hide sold out variants from collections and search.
