Frontmatter like its used with hugo is only helpful there but when using this tool on a single article it should be possible to ignore the frontmatter part
Maybe also use title from frontmatter for <head><title>.
Other infos like tags or date might also be intersting in <head> (date can work like versions).
This might also be interesting as <footer> content
