-/// The iOS example: one app with a Central tab and a Peripheral tab. The Central tab scans, lists
-/// peripherals, connects, and reads a characteristic; the Peripheral tab publishes a service,
-/// advertises, and serves reads, writes, and notifications. In the iOS Simulator armed by the SimBLE
-/// helper, both reach the host Mac's radio; on a device they drive the device radio.
+/// An interactive Bluetooth Low Energy console. The Central tab scans, connects, reads, writes,
+/// and subscribes; the Peripheral tab publishes a configurable GATT service, advertises, and
+/// serves it; the History tab is the unified trail. Results land with haptic and toast feedback.
+/// Each call is the real native one; the same actions run unchanged on a device, and in the
+/// Simulator armed by the SimBLE helper they reach the host Mac's radio.
 ///
 /// Launch environment (read at startup, all optional):
 ///   SIMBLE_AUTOSCAN       central starts scanning when it reaches poweredOn.
 ///   SIMBLE_AUTOADVERTISE  peripheral starts advertising when it reaches poweredOn.
-///   SIMBLE_TAB=peripheral open on the Peripheral tab (default Central).
+///   SIMBLE_TAB            open on "peripheral" or "history" (default central).
+///   SIMBLE_DEMO_SEED      publish, advertise, and bump the counter at launch for screenshots.
