Every ZIM file should have a layout page to define how the full HTML content should look like. It is also used to combine article header and article text.
Please note that specific readers, eg. on mobile phones, will ommit the layout page and just use their own, simplified HTML layout to display the pure article text only.
CAUTION: this is in draft status! The placeholders defined here are not yet implemented and might change!
<html> <header> <%B/<%title%>%> </header> <body> <%A/<%title%>%> </body> </html>
