  title 'Bounding Box Indentation'

  text do
    prose <<~TEXT
      Sometimes you just need to indent a portion of the contents of a bounding
      box, and using a nested bounding box is pure overkill. The
      <code>indent</code> method is what you might need.

      Just provide a number for it to indent all content generated inside the
      block.

  example new_page: true do
    text 'No indentation on the margin box.'
    indent(20) do
      text 'Some indentation inside an indent block.'
    end
    move_down 20

    bounding_box([50, cursor], width: 400, height: cursor) do
      transparent(0.5) { stroke_bounds }

      move_down 10
      text 'No indentation inside this bounding box.'
      indent(40) do
        text 'Inside an indent block. And so is this horizontal line:'

        stroke_horizontal_rule
      end
      move_down 10
      text 'No indentation'

      move_down 20
      indent(60) do
        text 'Another indent block.'

        bounding_box([0, cursor], width: 200) do
          text 'Note that this bounding box coordinates are relative to the indent block'

          transparent(0.5) { stroke_bounds }
        end
      end
    end
