+// One product custom field of type `file` (see x-product-custom-fields).
+// Uploads the photo to the storefront's own endpoint (CustomFieldUploadController)
+// as soon as it's picked, then writes the returned opaque reference into the
+// hidden input the add-to-cart form actually submits — the checkout module
+// never receives the file itself.
+//
+// While uploading, the file input is marked invalid via setCustomValidity(),
+// so the browser's own form validation blocks add-to-cart until the reference
+// is in place. A failed upload clears the input, so `required` blocks it too.
