The later post-Pentecost Sundays' real Nocturn 2 patristic content isn't
keyed by Pentecost offset in the reference engine — it's keyed by civil
calendar month/week (the old "Scriptura occurrens" cycle), which shifts
relative to post-pentecost-NN every year depending on Easter's date. Port
Date.pm's monthday() algorithm (pre-1955/Tridentine rubrics) as a new,
date-driven id, author all 20 August-November month-week files from the
reference engine's Tempora/0MN-0.txt sources, and pool them in
hours/matins.ts as a third, independent reading source alongside the
existing temporalId lookup.
