+{# Category-filter sidebar for admin product listings. Clicking a category
+   reloads the page with `?category=<id>` so the table server-side filters to
+   that category and its descendants. Expects in context:
+   - category_groups: [{ id, name, count, children: [{ id, name, count }] }]
+     (from views::shop::admin_category_groups)
+   - selected_category: "all" | "none" | "<id>" — the active filter
+   - total_count, uncategorized_count: ints
+   - category_base: page path, e.g. "/admin/catalog/products"
+   - category_suffix: extra query appended after the category param, e.g.
+     "&audience=business", or "" — set by the including template.
+
+   The link treatment mirrors shop/_sidebar.html (Penguin UI), but active state
+   is server-driven via aria-current (these links share a path, differing only
+   by query, so markActiveNav() can't pick the active one — hence no data-nav).
