let (word_count, reading_time) = get_reading_analytics(&page.raw_content);

Currently, the reading analytics are derived from page.raw_content which is all content (including footnotes). In order to get the word count for just the main content, the footnotes will need to be differentiated from the rest of the contents in raw_content.
