Android rations allow-while-idle wake-ups per app in doze, and the timer's
expiry slot and the alarm's fallback share that ration, so a 07:00
wake-up fire could hold back a timer due at 07:04. The bedtime slot is
now a plain exact alarm that doze may defer, which can move a mode
boundary but never a ring. A restore of unchanged bedtime settings no
longer forces the mode, and the screen skips its rule check while bedtime
is off.
