# The firmware drives the WDT peripheral directly (NRF_WDT, ported verbatim from
# the Arduino setup()/loop()), so Zephyr's watchdog driver is left out to avoid
# double-ownership of the peripheral.

# Microsecond timing for the RF poll busy-waits comes from a dedicated 1 MHz
# nrfx TIMER in the compat layer (the kernel RTC tick is too coarse), so the
# kernel clock is left at its board default here.

# Reasonable main stack for the cooperative loop + protocol state.
