+ * Cluster A Playwright sweep — minimal happy-path proving the
+ * `@suaveplan/packer-browser` Service Worker registers and intercepts a
+ * packed URL. The broader multi-browser sweep + diagnostics + range
+ * scenarios live in Cluster C.
+ *
+ * This spec is intentionally executable as a smoke test only; it depends
+ * on a real HTTP server hosting the SW bundle and a `*.packed` resource,
+ * which is set up out-of-band (Cluster A does not bundle a static
+ * harness — see the package README's "Test plan" footer).
