 * Tally.
 *
 * Light is the default because the usual moment is a bright kitchen at half
 * eight. Dark follows the phone's own setting rather than a toggle in here.
 *
 * Outcomes are never distinguished by colour. In the calendar they differ by
 * shape, so nothing reads as a red day or a green day. This is a shared record
 * of an agreed plan, and it may be read over a shoulder.
