def cleanup
  clean_temp_files
end

#prepare(options) ⇒ Object

Renders the template and any header/footer templates WITHOUT invoking wkhtmltopdf, returning { html:, options: } suitable for Document#pdfs_from_strings. Header/footer tempfiles referenced by the returned options stay alive until #cleanup is called, which must happen after the PDFs have been generated.

Defaults (layout, template) match #render's render :pdf path, so a prepared document converts identically to a single render.
