+//! Status protocol for the MMX 150 wireless dongle (reverse-engineered).
+//!
+//! Placeholder: the dongle rejects `GET_FEATURE`/`GET_INPUT` control
+//! transfers, so the status query is a write-then-read exchange over the
+//! vendor output/feature reports. The exact command bytes and the response
+//! layout for battery level and headset link state are being determined in
+//! Phase 1 (see `src/bin/probe.rs`).
+
+/// Vendor output report IDs available on the dongle.
