+ * 8s is far above any healthy response here (every other endpoint on this page
+ * answers in ~60ms) so a timeout means something is genuinely wrong, and the
+ * catch then reports it instead of the UI quietly missing a feature.

+ * ⚠️ It was 20s, and that made the abort UNOBSERVABLE: the e2e assertion that
+ * watches for the pin badge gives up at 15s, so the timeout fired after the
+ * test had already failed and the catch never ran within the window. A bound
+ * must fit inside the bound that contains it — the same arithmetic error as a
+ * retry that outlasts its job cap. Keep this below the 15s expect timeout in
