Dockerfile

# Custom docker image for DeTikZify. The default HF Spaces GPU image installs a
# tex live version that is too old for our needs, so we install the correct one
# ourselves. This simplified Dockerfile is based on an intermediate image
# (./Dockerfile.base) that already has Tex Live and pyenv installed, thereby
# greatly improving build time. It also defers preloading of detikzify models
# to runtime to avoid OOM errors.
