            Only one stack can be used by the firmware at a time, so only the selected
            stack's sources are compiled. Headers of the unselected stack remain visible
            but its symbols are not linked: the application must not call the other
            stack's API.

            help
                Aliro (Matter) reader stack: NFC + BLE access protocol, step-up, and the
                BLE transport (BleFlow / BleChannel / BleLink adapter).

        config DDK_PROTOCOL_HOMEKEY

                Apple HomeKey reader stack: NFC flows and HAP provisioning glue
                (HK_HomeKit). Excludes the Aliro and BLE transport sources.

            If enabled, DDK_LOG_HEX will output the full binary data instead of redacting it.
            WARNING: This may leak sensitive cryptographic keys (e.g., HomeKey/Aliro keys) 
            to the serial log. Use only for local development and debugging.
