/**
 * Checkpoints an in-progress Farmhand Shuffle match. This should only be
 * called by `FarmhandShuffleView` at the two "idle, waiting on the human
 * player" machine states - not on every transient mid-action state - so a
 * hard crash mid-action resumes from the last idle checkpoint rather than
 * losing more progress than necessary.
 *
 * Callers should follow this up with `handlers.persistState()` to flush the
 * checkpoint immediately, rather than waiting for the next day-advance
 * persistence cycle.
