Keep listed published rules public and guest-claim rules unlisted, with semantic document markup and share chrome that stays clickable.

Guest publishes remain share-by-link but stay out of the catalog and sitemap, and their pages send noindex until claimed. The published-rule view now uses heading and list markup matching Markdown export, and top banners sit below the header so Share is not covered.
