This note reads like it applies to all ox sandboxes, but only the Docker base image is updated in this PR. Cloud sandboxes are built via sandbox/cloud-base-steps.yaml (which currently doesn't install bubblewrap), so Codex sessions on the cloud provider may still lack /usr/bin/bwrap and show the warning. Please either scope the docs to the Docker provider/base image or ensure the cloud base snapshot also installs bubblewrap.

In Docker-based sandboxes, ox's base image installs system `bubblewrap`, so Codex can use `/usr/bin/bwrap`
without printing its vendored-bubblewrap fallback warning at session startup. Other sandbox providers may not have `/usr/bin/bwrap` available and can still show this warning.
