//! Every file the site serves, built once per refresh into one map.
//!
//! GUN-GUEST (owner 2026-10-30): no HTML page of the site's own is left. A repository's
//! address is the console's (its document, with the page's content pre-rendered into it:
//! [`crate::shell`]); what is built here is robots.txt, the sitemap, llms.txt,
//! llms-full.txt, each public repository's readme.md, tree.txt and issues.md, IndexNow's key
//! file, and the console's own landing at `/` with the search tags in its head.
