// A reading's `label` (the "Léctio libri..." incipit) previously looked up
// bible-book-incipits.ts's canonical-abbreviation-only table using the raw
// book abbreviation from data/hours/bible-plan/*.yml -- which, for ~30
// books, is one of scripture/index.ts's own English-style aliases (e.g.
// "jdt" for Judith), not the canonical form ("jdth") that table is keyed
// by. The alias resolved verse *text* fine (getScriptureChapter already
// consulted the alias table) but silently missed the label lookup,
// rendering as the generic "Reading" heading instead -- live case: Sept
// 18 2026's own Ember Friday commemoration, `post-pentecost-16-friday`'s
// first reading (Judith 11-13). Fixed 2026-09-03 by routing both the
// incipit and responsory lookups through scripture/index.ts's own
// `canonicalBook`, the same normalization the text lookup already used.
