Subject: [PATCH] fix(ci): deploy docs via the GitHub Actions Pages pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pages source is 'GitHub Actions' but docs.yml used mkdocs gh-deploy (branch push), which a workflow-source Pages ignores — the site was stalled. Switch to mkdocs build --strict -> upload-pages-artifact -> deploy-pages.
