### Docker-bygget
Backend-Dockerfilen använder nu projektets rot (`.`) som byggkontext. Converter-biblioteket kompileras i en separat stage:
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/`

> **OBS:** `backend/package.json` har `"recipe-document-converter": "file:../recipe-document-converter"` för lokal utveckling. I Docker-bygget ignoreras den file-referensen — convertern kopieras in manuellt från converter-build-steget.
