/* Prototype PCB service revision: Nordic QFAA package pin7 is P0.05.
 * R25 retains the external 1.8V pull-up: input/high is charge-disabled.
 * Set OUT high before configuring output, validate battery temperature,
 * then drive low to allow charging. Assert high before sleep/recovery.
 * This pin configuration is not a completed or hardware-tested ring app.
