* # Deadline Face
*
* This is a watch face for tracking deadlines. It draws inspiration from
* other watch faces of the project but focuses on keeping track of
* deadlines. You can enter and monitor up to four different deadlines by
* providing their respective date and time. The face has two modes:
* *running mode* and *settings mode*.
*
* ## Running Mode
*
* When the watch face is activated, it defaults to running mode. The top
* right corner shows the current deadline number, and the main display
* presents the time left until the deadline. The format of the display
* varies depending on the remaining time.
*
* - When less than a day is left, the display shows the remaining hours,
* minutes, and seconds in the form `HH:MM:SS`.
*
* - When less than a month is left, the display shows the remaining days
* and hours in the form `DD:HH` with the unit `dy` for days.
*
* - When less than a year is left, the display shows the remaining months
* and days in the form `MM:DD` with the unit `mo` for months.
*
* - When more than a year is left, the years and months are displayed in
* the form `YY:MM` with the unit `yr` for years.
*
* - When a deadline has passed in the last 24 hours, the display shows
* `over` to indicate that the deadline has just recently been reached.
*
* - When no deadline is set for a particular slot, or if a deadline has
* already passed by more than 24 hours, `--:--` is displayed.
*
* The user can navigate in running mode using the following buttons:
*
* - The *alarm button* moves the next deadline. There are currently four
* slots available for deadlines. When the last slot has been reached,
* pressing the button moves to the first slot.
*
* - A *long press* on the *alarm button* activates settings mode and
* enables configuring the currently selected deadline.
*
* - A *long press* on the *light button* activates a deadline alarm. The
* bell icon is displayed, and the alarm will ring upon reaching any of
* the deadlines set. It is important to note that the watch will not
* enter low-energy sleep mode while the alarm is enabled.
*
*
* ## Settings Mode
*
* In settings mode, the currently selected slot for a deadline can be
* configured by providing the date and the time. Like running mode, the
* top right corner of the display indicates the current deadline number.
* The main display shows the date and, on the next page, the time to be
* configured.
*
* The user can use the following buttons in settings mode.
*
* - The *light button* navigates through the different date and time
* settings, going from year, month, day, hour, to minute. The selected
* position is blinking.
*
* - A *long press* on the light button resets the date and time to the next
* day at midnight. This is the default deadline.
*
* - The *alarm button* increments the currently selected position. A *long
* press* on the *alarm button* changes the value faster.
*
* - The *mode button* exists setting mode and returns to *running mode*.
* Here the selected deadline slot can be changed.
