89-89: ⚠️ Potential issue | 🟡 Minor

Pre-existing: Production workflow references DockerfileDev.

This workflow is named "Production Build & Deploy" and now targets the production environment, but the Docker build uses ./docker/DockerfileDev. If there's a separate production Dockerfile (e.g., DockerfileProd), this should be updated. If this is intentional, consider renaming the file to avoid confusion.
