/**
 * Katalog-Generator — AR-5
 *
 * Erzeugt zwei Artefakte aus catalog.ts (Single Source of Truth):
 *
 *   colorVarietySeed.generated.json  — Display-Notation (Klammer: e[f]/c[chm]/c[h])
 *                                       → Quelle für UI-Dropdowns, Frontend-Suche.
 *
 *   colorVarietySeed.backend.json    — Frozen internal symbols (ef/cchm/ch)
 *                                       → Quelle für künftige EF-Seed-Migrationen (Pam).
 *                                       NICHT in Bracket-Notation ändern — Backend-Parser
 *                                       erwartet frozen symbols (CR-11-Matcher-Guardrail).
 *
 * Ausführen nach jeder Änderung an catalog.ts:
 *   npm run gen:catalog
 *
 * Der vitest-Drift-Guard (catalog-drift.test.ts) schlägt fehl, wenn
 * generated.json veraltet ist — Fehler macht den fehlenden Generator-Lauf sichtbar.
