     3. collections[handleize(vendor)-1]                 (Shopify dup suffix)
     4. product.vendor | url_for_vendor                  (original search URL)
 
+  Existence test uses `collection.id` — Shopify returns an EMPTY collection
+  drop (id == nil) for a missing handle, so `collections[h] == empty` is
+  unreliable; `.id` is the robust truthiness check.
+
   Usage:
-    {% render 'dw-vendor-collection-url', vendor: product.vendor %}
-  Returns the URL as inline output (assign-and-capture at the call site).
+    {% capture u %}{% render 'dw-vendor-collection-url', vendor: product.vendor %}{% endcapture %}
+    <a href="{{ u | strip }}">…</a>
 {% endcomment %}
