# NAWI reporter — Hugging Face Docker Space
#
# Docker rather than the Gradio SDK because the frontend wants a plain
# REST API, not Gradio's two-step queue protocol, and because LibreOffice
# needs a root apt install.

FROM python:3.11-slim

# LibreOffice Writer is the PDF converter. It is a large install, so it
# goes in its own layer and gets cached across rebuilds.
#   fonts-dejavu / liberation  keep the report's typography stable; without
#                              them LibreOffice substitutes and the tables
#                              shift.
