Path A (fully wireless: BT Classic host + BLE HID peripheral) is the chosen architecture. Bridge will be self-powered off a LiPo in a 3D-printed case and sit next to the phone — no cables to the phone at all. Hardware picked: ESP32-WROOM-32 USB-C dev board (original ESP32 silicon, has BT Classic, CP2102 onboard). Path B (USB-CDC serial) kept in the doc as a fallback if dual-mode BT coexistence proves painful during bring-up.
