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.
