/**
 * One-off generator, run by hand whenever the catalog's reference data
 * changes (a new ingredient/diet/allergen added to
 * `db/reference-seed-data.ts`, or an English key corrected in
 * `catalog-en-keys.ts`): regenerates
 * `apps/web/src/locales/fr/translation.json`'s
 * `catalog.{diets,allergens,ingredients}` sections (English key -> French
 * label), merged in without touching the rest of the file.
 *
 * Doesn't touch the database — a brand new diet/allergen/ingredient is
 * created fresh by `seedReferenceData`'s normal create path (see
 * `reference-seed-data.ts`), no backfill needed. Renaming an *existing*
 * item's English key in `catalog-en-keys.ts` does need a one-off migration
 * (`UPDATE ... SET key = ...`, keyed by the *old* key value) written by
 * hand for that occasion — see
 * `prisma/migrations/20260818193000_catalog_keys_to_english/` for the shape
 * one looks like.
 *
 * Never imported by the app itself — a dev-time tool, run via
 * `tsx scripts/generate-catalog-i18n.ts`.
