# CI builder image for Love2D projects: packaging tools + luac syntax check,
# with love.js pre-fetched to /opt/lovejs.zip so `make web` does not hit
# GitHub on every pipeline run (the Makefile falls back to curl elsewhere).
#
# Build & push (the CI runner is linux/amd64):
#   docker build --platform linux/amd64 -f builder.Dockerfile \
#     -t git.teletypegames.org/internal/love-builder:latest .
#   docker push git.teletypegames.org/internal/love-builder:latest
