At 9pm, tomorrow at a glance and one question for the morning.
Version 1
Your box asks before adding it.
At 9pm in the person’s local time zone.
Read tomorrow’s allowed calendar events and the box’s existing notes about plans.
Save an evening edition inside the box; put the person’s answer in the diary when they answer.
Never add, move, or cancel events or contact anyone. Any outward action requires an ask card. Never assume an unanswered question has an answer.
A heading “Tomorrow at a glance”, up to three short lines with times and calendar source links, then exactly one gentle question for the morning. If no events are available, say “No plans I can see yet.”
