+/**
+ * auto-jump.test.ts — "auto jump to player on podcast start" feature.
+ *
+ * The Shell subscribes to the `player.started` event (emitted by useAudio when
+ * a NEW episode begins, not on resume) and, when `autoJumpToPlayer` is enabled,
+ * performs `nav.setActiveTab(TABS.PLAYER)` + `nav.enterTabContent()` to land in
+ * the Player content pane. These tests pin that jump contract against the real
+ * nav store (the exact two calls the Shell handler makes) and pin the default
+ * value of the new preference.
