+Backend-Dockerfilen använder projektets rot (`.`) som byggkontext. Bygget sker i tre steg:
+
+1. **converter-build** — Kompilerar `recipe-document-converter` till JavaScript + typdeklarationer
+2. **builder** — Installerar backend-beroenden, kopierar in den kompilerade convertern till `node_modules/`, genererar Prisma-klient och bygger NestJS-appen
+3. **runner** — Minimal produktionsimage med enbart `dist/`, `node_modules/` och `prisma/`
