# NOT used by the Hugging Face Space.
#
# The Space is `sdk: static` (see README.md's front matter), because creating a
# Docker Space requires a paid Hugging Face plan. This file exists for two
# reasons:
#
#   1. running upstream unmodified in a container locally, where app.py serves
#      the real API and the browser overlay is not involved at all;
#   2. as the starting point if this ever moves to a paid plan.
#
# Read the caveat before reaching for reason 2: a Space's filesystem is
# ephemeral. Upstream stores documents in uploads/ and review records in
# data/reviews.json, so a restarted container starts empty. Making the Space a
# real review system needs a persistent volume or an external store, not just
# this Dockerfile.
#
# Upstream needs no third-party packages, so there is nothing to install.
