What is the actual difference?
I think you are using a slightly different character.

This is very hard to spot, we should document it well

There can only be 1 set of frontmatter in a markdown file.

To Myself,

• 1. Add a rule in the GitHub validator to check for multiple sets of frontmatter blocks

In this rule (about frontmatter) we are using the --- frontmatter symbols multiple times. Which is causing the error. To fix this we are using a Greek character that looks exactly the same instead. (See below chi character)
