8/**
9 * A paper's markdown twin at `/research/publications/<slug>.md`, read from the same row as its page
10 * (app/lib/publications/twin.mjs builds it), so an agent reads the facts a person does and an edit through
11 * Carrel reaches both at once. A draft answers 404 like its page.
12 *
13 * It was a static asset until publications moved to D1, which is why its headers lived in public/_headers.
14 * They are here now, with the cache tag a save purges. NOINDEX because a paper page is a Scholar submission
15 * and a second indexable URL with the same title and abstract is the duplicate that costs it its ranking;
16 * the twin is for agents, and llms.txt is where they are told about it. The canonical link names the page.
