I'm not 100% sure what you are trying to accomplish, but I am guessing
that you want to provide some parameters to all of your runmode
templates.  If that isn't what you want, maybe reword your question.

Why is this defined in the global scope?  That is often a sign of a problem.

The teardown phase happens after the page has already been sent to the
browser.  So doing anything with the template will not do anything
useful.

The easiest way to add template parameters to all of your templates is
to override the load_tmpl method.

sub load_tmpl {
  my $self = shift;
  # Call the real load_tmpl to get a template object
  my $template = $self->SUPER::load_tmpl(@_);
  # add a parameter
  $template->param(graphic => 'header.gif');
  return $template;
}

Cheers,
