+ * Cluster C Playwright sweep — content-addressed URL invalidation.
+ * Registering a SW configured with `contentAddressed: true` MUST delete
+ * every previously-installed cache whose name starts with the
+ * configured prefix and is not in the `keep` list. The page-side
+ * harness exposes `/sw-cache-names` to read the live cache names.
