Close out the Matins per-book responsory pool: 59 of 72 books

Asked to translate the 15 remaining "real Latin, no English" books.
None needed translation: the whole post-Epiphany reading season
(Galatians/Ephesians/Philippians/Colossians/1-2 Timothy/Titus/
Philemon/2 Thessalonians) turns out to have no distinct responsory
content of its own -- every feria file references 2 Corinthians' own
week (already bilingual) by weekday position. Same for 2 Peter/2-3
John/Jude, which reference Ascension Day's own responsories (act).

Only Romans genuinely has nothing: every citing file borrows an
unrelated feast's own proper responsory (Circumcision, Christmas Day,
a January saint), never anything Romans-specific. Left unseeded --
using one would repeat the Sacred Heart/Jeremiah mismatch this pool
already avoids elsewhere.

59 of 72 books now seeded -- every book with any usable Latin content
in the source at all. The remaining 13 (Romans plus 12 books with no
citation anywhere) are the real, final gap.

Ran the full canonical-key audit again; confirmed clean. npm test
(2025 passed) and tsc --noEmit pass; live-verified through
getBiblePlanReadings.

+### Matins responsory pools: the "untranslated 15" turned out mostly already bilingual (2026-09-04)
+
+Asked to translate the 15 "real Latin, no English" books. Before translating anything, re-checked
+each one's own `@Tempora/X:ResponsoryN` reference chain (the same technique that unblocked 8 books
+earlier the same day) — and found the whole post-Epiphany "ordinary time" reading season (weeks
+3-5, covering Galatians/Ephesians/Philippians/Colossians/1-2 Timothy/Titus/Philemon/2
+Thessalonians) doesn't have its own distinct responsory content at all: every one of its 21 feria
+files `@`-references 2 Corinthians' own week (Epi2-0 through Epi2-6, already fully bilingual from
+earlier this same day) by weekday position. Confirmed by reading every week-3/4/5 feria file's own
+`@`-line directly, not guessed. Same story for 2 Peter, 2-3 John, and Jude — all four `@`-reference
+Ascension Day's own responsories (already seeded as `act`). **None of these 12 books needed any
+translation at all** — added `gal`/`phil`/`1tim` (share Epi2-1), `col`/`2tim` (share Epi2-2),
+`eph` (Epi2-3), `1thess`/`tit` (share Epi2-4), `2thess`/`phlm` (share Epi2-6), `2pet`/`2joan`/
+`3joan` (share `act`'s R1), `jud` (`act`'s R7) — all real, already-transcribed bilingual text.
+
+Also fixed a real, separate bug the user caught by eye in the rendered app: `getResponsoryForBook`'s
+`joinResponsory` concatenated the pool's `r`/`v` text with a bare newline and no "R."/"V." labels
+at all — every other responsory source in the app (`octave-readings.ts`'s own `responsory` field,
+every `nocturn-readings/*.yml`'s inline `responsory`, and the new per-Common-category pool) uses
+the full "R. ...\n* ...\nV. ...\nR. ..." convention. Fixed by computing the repeat line from the
+`*` marker already present in the pool's own `r` text (a separate commit, `1867f73`, before this
+content pass).
+
+**Only `rom` (Romans) turned out to have no content to translate at all**, on inspection — re-
+checked every one of its 15 citing files (all in the Christmas-Octave `Nat0X` range): every single
+one `@`-references an unrelated feast's own proper responsory (Circumcision, Christmas Day, or a
+January 7 saint), never anything Romans-specific, standalone or borrowed. There's no genuine
+"Romans content" anywhere in this reference source to translate, sourced or original — using one of
+these borrowed responsories would repeat the Sacred Heart/Jeremiah mismatch this file already
+avoids elsewhere. Left `rom` unseeded; it would need an entirely original composition, not a
+translation, if ever wanted.
+
+59 of 72 bible-plan books now seeded — every book with any genuinely usable Latin at all. The
+remaining 13 (`rom` plus the 12 already-confirmed-absent books) are the real, final gap: `rom` has
+no book-specific content anywhere in this source; the other 12 have no citation anywhere at all.
+Ran the full canonical-key audit again (programmatic check against `BOOK_ALIASES`, per the
+established lesson) — confirmed clean. `npm test` (2025 passed) and `tsc --noEmit` both pass;
+live-verified through `getBiblePlanReadings` (`post-epiphany-3`/Wednesday `Gal`, `post-epiphany-5`/
+Monday `1tim`, `sunday-after-ascension`/Saturday `Jude` all resolve real responsory text; `Ruth`
+correctly still resolves `undefined`).
