nice-to-have: SEO optimized header values in title tag for wiki, cards and articles
I suggest insert
SEO optimized header values
in title tag for wiki, cards and articles. Similar to header values in title tag for webpages or posts in Hubzilla stream. S. also "SEO: ABC des suchmaschinenoptimierten Publishings mit Hubzlla" https://hub.libranet.de/articles/nmoplus/seo-abc-des-suchmaschinenoptimierten-publishings-mit-hubzilla (german).
