d0955aa69dTwo composite actions extracted from modelcontextprotocol's blog-preview workflow: - deploy: injects noindex headers/meta, deploys to CF Pages under a per-PR branch alias, posts/updates a sticky PR comment with preview URLs - cleanup: deletes all CF Pages deployments for the PR branch alias on close, updates the sticky comment Callers provide a pre-built static HTML directory; the actions handle everything Cloudflare-specific.
