Problem

Because the office day starts the evening before, the evening of a given civil day may belong to the First Vespers of the morrow. The assembler must render the correct Vespers per the boundary.

Acceptance criteria

  • Evening resolves to First Vespers of the morrow when due
  • The correct day's antiphons and collect are used
  • The boundary matches the calendar engine's semantics
  • Tests cover an eve where Vespers belongs to the next office day

Notes

Reuses the v0.1.0 liturgical-day boundary.
