- The backup record's fallback RX pin is 35, as the radio's default is.
- BootPins.h, pins.js and Transceiver.cpp say to keep the pins, the radio
pins checked and the shared RX/TX rule in step.
- index.js reads the chip model through one chipModel().
- BootPins.RADIO is RADIO_PINS; the P4 test builds its config once.

GPIO12 is a strapping pin on the original ESP32: high at reset, it powers
the flash at 1.8 V. A CC1101 can hold GDO2 high at power-up, so a board
with RX on 12 bootloops after a power cut until EN is pressed. It was the
default RX pin.
- RX defaults to GPIO35 on the original ESP32. Saved settings keep their
pins.
- The log warns each time the radio starts, and the radio settings show a
warning, while TX, RX or MISO is on a pin whose level at reset can stop
the chip booting (src/BootPins.h, data-src/js/pins.js).
