Uploaded .docx files are converted to PDF on the server using a Gotenberg sidecar before entering the normal envelope pipeline. The feature is opt-in via NEXT_PRIVATE_DOCUMENT_CONVERSION_URL; when unset, only PDF uploads are accepted. A per-process circuit breaker opens for 30s after a conversion failure to shed load. Ships a dev Dockerfile that layers Microsoft Core Fonts and additional language fonts onto the upstream Gotenberg image for better fidelity.
