Thanks Jonathan,

For anyone else interested, I just discovered wrapping the call like this works:

if ( $export ) {
    $m->clear_buffer;
    $m->comp('/csv', csv_data => $results, filename => 'results.csv' );
    $m->abort;
}


...it now delivers the file without headers/footers defined in
./pages/autohandler.
