potiuk pushed a commit to branch preserve-previous-theme-versions
in repository https://gitbox.apache.org/repos/asf/airflow-site.git

commit f3877872a67243e8069cc2c9f11a04fd7d48e052
Author: Jarek Potiuk <ja...@potiuk.com>
AuthorDate: Mon Mar 16 23:49:56 2026 +0100

    Preserve previous sphinx_airflow_theme versions in CI builds
    
    The build-site step runs `rm -rf dist/*` which wipes old theme packages
    from the publish branch. Save them to /tmp before build and restore after.
