/**
 * Web Bluetooth-backed `SensorDeviceClient<TReading>`. A single generic
 * client wraps either of `@dg-kit/protocol`'s sensor adapters
 * (`PawPrintsSensorAdapter`, `CivetPressureSensorAdapter`) — they share the
 * exact same `WebBluetoothSensorAdapter<TReading>` shape
 * (onConnected/onDisconnected/getState/subscribe/onStateChanged), only their
 * LED-setting method name differs (`setLedSolid` vs `setIndicatorColor`),
 * which is why `setIndicatorColor` is threaded in as a constructor callback
 * rather than called directly on the adapter.
