Every notification gets a tile in the colour of what it is about (a trip, a
message, a booking, packing, a to-do, Vacay, a collection, shared photos, a
tour, an update or an alert) with the sender's face on its corner, the page
and the bell's panel group the list under Today, Yesterday, the weekday or
the date, and answering or following a notification is a proper button.
The server's UTC timestamps are read as UTC for the grouping and the time.
