# local cargo cache mounts, so it cold-compiles the whole binary every run
# (>5 min) and blows past the 200 s stack-setup timeout. The CLI build uses the
# `builder-cache` stage and the shared cache mounts, so it recompiles only what
# changed (seconds on a warm cache); we then hand the tag to the fixture via
# $OXICLOUD_IMAGE, which makes it skip its own build entirely.
