# Reusable kind-based e2e pipeline, split into two jobs so the disk-heavy build
# and the kind test run never share a runner. The build job compiles the
# controller + e2e images and exports them as tarballs; the test job loads those
# tarballs into kind and runs the suite, needing no Go toolchain or buildx.
