Personas are close to stories (stored as /readme/md files).
Work needed:
find how to render the readme.md file into html, along with the .md
provide access (dedicated page) to the list of personas (probably not with a _data/personas.yml, because of spaces in names, a loop over stories should be enough)
Readme files are now rendered, with a small metadata field to help grouping by persona.
The stories page has been rewritten, with a "grouping layout".
See 01be47d.
As the summary says. Later, we can then group stories by personas
