I’m afraid @page isn’t available in the version of WebKit that Marked has to use, and it appears there will be no future development on that version. Hopefully Apple will fix some issues in the new version that will allow Marked to make use of it.
As far as post processing, it’s not currently an option but I’m considering it for the future. One option is to use tee in a custom processor to output to a file in parallel with the preview.
