Microformats are the public page's API for other sites (potluck first): each bookmark is an h-entry with u-bookmark-of, p-name, p-summary, a p-category per tag (linked to a tag search), dt-published (bookmarked) and dt-updated (last edited). Prev/next links carry rel=prev/next, so a reader can follow a filter's pages. Tests parse the page with microformats-parser to pin the contract. Generated-by: Claude Opus 5.5
