FROM rust:1.88-bookworm AS builder

# The build context has no `.git/` (see `.dockerignore`), so `build.rs` cannot
# discover the commit and `--version` in the running container would name only
# the crate version. Whoever starts the build does know the commit, so they pass
# it: `make docker` does this from `git rev-parse`. Left unset, both arrive as
# empty strings, which `build.rs` reads as "not given" and degrades exactly as a
# release tarball does.
