block at absolute beginning, then rewritten article HTML body text. No intro. Need to clean text: remove promotional lines, “SEE ALSO” links, footer junk. Also need to protect all media elements: keep tags? Actually there are figure tags with images, captions. Must keep and etc unchanged. But we need to remove promotional lines: There’s promotional line about book release: The Brain Cliff …. Also possibly “You write that …”. That’s part of article; maybe not promotional. “SEE ALSO” not present. Footer junk: maybe the last line “The Brain Cliff by Dr Norman Swan …” that’s promotional. Also maybe the first line “Let your mind wander, don’t retire and stop worrying: surprising ways to help save your brain from the cognitive cliff” is original headline, we need rewrite to unique fresh professional. So we need new headline.
