  # If we get here and template source doesn't start with one it means
  # that we are rendering partial named according to legacy naming convention (partials ending with '.mjml')
  # Therefore we skip MJML processing and return raw compiled source. It will be processed
  # by MJML library when top-level layout/template is rendered
