// A broad pantry list — the goal is to cover the large majority of what a
// home cook reaches for (viandes, poissons, légumes, fruits, féculents,
// condiments, épices...), not just enough to exercise the recipe catalog in
// tests. Ingredients are reference data (see `Ingredient` in schema.prisma:
// `name` is `@unique`, there's no create/update/delete endpoint), so this is
// meant to already be comprehensive at first deploy rather than grown
// piecemeal as recipes need more of it. `allergenNames` reference
// `ALLERGENS` above by name — every one of the 14 EU-regulated allergens is
// covered by at least one ingredient here.
//
// Grouped by (`category`, `subcategory`) — mirrors `IngredientCategory`/
// `IngredientSubcategory` in schema.prisma, a supermarket-aisle taxonomy
// ("rayons") reworked from an earlier, less intuitive scheme that mixed
// cuisine-of-origin buckets ("cuisine italienne") in with aisle-style ones
// ("légumes") — an ingredient's category used to depend on which angle you
// thought of first. The picker UI (`apps/web`'s `IngredientPicker`) uses
// this to offer category browsing, not just free-text search — with 400+
// ingredients, search alone doesn't scale to actually *finding* something,
// and a single flat list of 7 aisles alone wouldn't either (some aisles
// would be 100+ items deep). Each group's key is the single source of
// truth for that mapping; `INGREDIENTS` below just flattens it back to one
// array for the seeding loop.
//
// `defaultDiets`/`defaultIcon` are what every item in the group shares
// unless it sets its own `dietNames`/`icon` — most groups are homogeneous
// on both counts (a vegetable is always vegan and always looks like a
// vegetable; a cut of meat never is and never does), so this avoids
// repeating the same values on hundreds of items; only a group's
// exceptions (a fish-based stock inside "bases", a cheese inside "produits
// laitiers"…) need a per-item override.

 * point, `prisma db seed`) and by `test-support/reset-db.ts` (so every
 * test starts from the same realistic reference data the real app seeds,
 * not an empty table).
 *
 * Every `name` below (`DIETS`, `ALLERGENS`, `INGREDIENT_GROUPS`) is an
 * *authoring* label, never written to the database or seen by a client —
 * {@link getEnglishKey} resolves each row's real, stable, English `key`
 * from it (see `catalog-en-keys.ts` for why the key must be English even
 * though this file's labels are French). The database only ever stores
 * that key; the French label itself lives in `apps/web`'s
 * `locales/fr/translation.json` (`catalog.*`
 * namespace, kept in sync by `scripts/generate-catalog-i18n.ts`).
