 does NOT rewrite site-absolute links ("/style.css", "/zones/...") — only
 the sitemap's canonical URLs pick up base_url. This pass prefixes every
 href="/..." and src="/..." in the built HTML/SVG with the base's path
 part ("/Wiki") so the same build works under the subpath.

 Idempotent: values already carrying the path part are left alone. Protocol
 links ("//cdn..."), data: URIs, hashes and relative links never match.
