# GODOT_VERSION is a stable Godot release tag (e.g. "4.7.1", no "-stable" suffix — Godot 4.0+
# only, see docs/handoff/godot-ci-custom-image.md). BLENDER_URL is the tarball to bake in.
# .gitea/workflows/publish.yml always resolves both at build time via
# scripts/resolve-godot-version.sh and scripts/resolve-blender-url.sh. The defaults below are
# only a fallback for a plain local `docker build`.
#
# Godot itself is downloaded straight from its official GitHub releases (godot-builds), the same
# source barichello/godot-ci's own Dockerfile uses — this image no longer depends on that image
# as a base. Decided via wayfinder map https://git.arthurerlich.de/haylan/godot-ci/issues/2,
# ticket https://git.arthurerlich.de/haylan/godot-ci/issues/7: Alpine was considered and rejected
# (official Godot/Blender binaries are glibc-only, and Alpine's musl-native alternatives live
# only on its unpinned `edge` repo); a plain glibc-slim base doesn't cost the compatibility risk.
