 /**
  * The headline total, what qualifies it, and how it got there.
  *
  * Lives beside the other per-widget files rather than in `DashboardScreen` because the card now
  * assembles three separate things out of the state — the figure, one of three footnotes, and the
  * month's movement — and each of them is a decision worth reading on its own.
  *
  * [variant] stays a raw key until it reaches the widget that defines the treatments: see
  * [DashboardWidget].
