+  // The panel then coerced that Promise to "[object Promise]" in the

+  // await the path on the renderer side and cache it, then hand the panel
+  // a sync getter. This test mirrors that pattern: simulate the renderer's
+  // pre-resolve + cache, and assert the panel's persistence path is a
+  // real resolved string on mount.
