+// Summary: Debug-only menu items: load demo entries, the performance overlay and the on-watch benchmark.
+//
+// Release builds compile the empty (:release) module instead, so none of this
+// reaches the Store build. The benchmark is how the watch's real speed gets
+// measured (docs/PERFORMANCE.md): sideload a debug build and run it.
