# syntax=docker/dockerfile:1
#
# Hugging Face Space image for the GeoGuesser environment.
#
# Self-contained on purpose. The repo's own server/Dockerfile builds
# `FROM openenv-base:latest`, a locally built tag that does not resolve on the
# Hub, so this inlines the base image's steps instead. It also vendors
# `src/openenv` rather than installing a release, so the Space runs exactly the
# core this checkout runs -- the Gradio tab naming this environment relies on is
# newer than the published package.
#
# Imagery is NOT in the image: 22 GB cannot fit, and Space disk is ephemeral.
# It arrives through a Storage Bucket mounted read-only at /data.

# 3.12 to match the interpreter this environment is developed and tested on.
