I cant share the template itself, but here is a quick example:
# Here could be your content of page 1
# I designed the first header without a header tag. but i think u can do it the same way as below
# Forced PageBreak
<div style='page-break-before: always;'> </div>
#---- Second Page of the template -----
#(even over multiple pages) the header will be displayed inside this section .
# some css will be needed to align it the way you want. I deleted mine so we have a clean example.
# Header Content
#Content Page 2
At least pretty simple, but it took hours to find out. Hope it will be useful
