+ * unhandled rejections, so the app usually survives — but the reason lands on
+ * stderr alone, which is discarded entirely when the app is launched from
+ * Finder or the Start menu. Without a record in desktop.log, a main-process
+ * fault is invisible in a `hermes debug share` bundle and the user is left
+ * describing symptoms instead of showing a stack.
