Thirty minutes before wake time, the screen begins a slow sunrise. By the time there is anything to hear, waking is already underway.
Not an alarm. A character your child chose, saying their name, in a voice written for their age.
The voice returns, a little firmer each time. A gentle ladder, not a siren.
Then, and only then, your phone gets a nudge. That's the deal all day: you hear about exceptions, not operations.
