Each image has a matching `.elf` in `firmware/`. All AIO variants include the same
automatic Switch/XInput and manual USB output modes; no separate feasibility
firmware is needed. The wake-capture image remains a separate setup utility.
The default `python3 build.py` command and `firmware/switch-pico.*` artifacts remain the UART/Pico build. The AIO build requires `PICO_BOARD=pico2_w`; it is not interchangeable with the original non-wireless Pico firmware.

`build.py` automatically locates the Pico SDK and Arm GNU toolchain from valid

existing regular, AIO (including BLE/Classic), and wake-capture CMake caches, then from

finally from conventional user and system locations. A compiler already on
