rewriteLegacyImageUrlsInHtml only swapped URLs that had a mapping in
legacy-image-map.json — anything missing the map was left pointing at
the dead https://www.broadcastbeat.com/wp-content/uploads/ host (404
in browsers, bad for SEO, broken-image icons everywhere).
New stripDeadLegacyImages() pass runs after the rewrite and removes:
- <figure> blocks whose only inner image is a dead WP image
- <a> wrappers around dead images
- Bare <img dead> tags
- Empty <figure> leftovers
…leaving body copy intact and figcaption-less.
cleanLegacyImages() is the one-call helper that pipes both steps.
Applied via rowToArticle so every /news/<slug> render gets it.
