/**
 * PILOTBATCH – Receptkatalog Fas A (docs/32).
 *
 * Genererar ~20–30 recept över en skiva av matrisen:
 *   middag × mejeri/kyckling/köttfärs × allätare+veg
 *
 * Använder Gemini i staging/dev (AAMOS_MODE=gemini) eller mock (AAMOS_MODE=mock).
 * Ingen påfyllning i prod. Resultatet skrivs till stdout som JSON + markdown.
 *
 * Körning:
 *   AAMOS_MODE=mock pnpm tsx packages/recipe-generation/scripts/pilot-batch.ts
 *   AAMOS_MODE=gemini GEMINI_API_KEY=... pnpm tsx packages/recipe-generation/scripts/pilot-batch.ts
