Is there a way to designate manually the start of a content summary?
Just like how <!--more-->
is used to designate the end of content summary for markdown.
Ideally I would like to do something like this:
# Section
Crazy HTML markup here or maybe a shortcode....
<!--begin-summary-->
summary content
<!--end-summary-->`
The problem with existing method is when using a hook for rendering markdown headlines any HTML injected to style a header ends up leaking into the page summary variable, which I don’t want.
