(** The EF lectionary resolution chain. All rubric knowledge about what a day
    with no proper falls back to lives here, not in the kernel.

    Steps 1 and 2 only (Task 4): the observed celebration's own proper, else
    the day's own temporal slug in the lectionary. A day matching neither
    gets [] for now -- the ferial fallback to the preceding Sunday (Task 5)
    and the Commons (Task 6) are not built here. *)
