- migration 202610280004: image_file_no, kind, published_at and parent_refs on the slot table; the image, News, IndexNow and HTML sitemap settings - the rebuild stores each page's featured and body images (absolute on the site, deduplicated, at most 1000) and numbers the rows with images into sitemap-images-<n>.xml with the per-type files' stable rules - the index lists the image files while images_enabled is on; the files route serves them with image:image and image:loc only
