Shopify Canvas themes

Add the Genlook virtual try-on to my product page. Canvas themes cannot turn on app embeds yet, so add it to the theme code:

1. Create a snippet named genlook-tryon.liquid with exactly the code below, unchanged, and render it once in the product template.
2. Add a "Virtual Try-On" button to the product page, right above Add to cart. Style it like my theme's secondary button, full width. Give the button the class genlook-custom-button, and make a click call window.Genlook.cabin.open(). Translate the label into my store's languages.
3. Do not change anything else.

```liquid
<script>
  window.Genlook = window.Genlook || {};
  window.Genlook.cabin = window.Genlook.cabin || { open: function (p, o) { window.Genlook.cabin._pending = [p, o]; } };
</script>
