    prose <<~TEXT
      Stamps should be used when you have content that will be included
      multiple times in a document. Its advantages over creating the content
      anew each time are:
    TEXT

    ordered_list(
      'Faster document creation',
      'Smaller final document',
      'Faster display on subsequent displays of the repeated element because ' \
        'the viewer application can cache the rendered results',
    )

    prose <<~TEXT
      The <code>create_stamp</code> method does just what it says. Pass it a
      block with the content that should be generated and the stamp will be
      created.

      There are two methods to render the stamp on a page <code>stamp</code>
      and <code>stamp_at</code>. The first will render the stamp as is while
      the second accepts a point to serve as an offset to the stamp content.
