<!-- Sitemap index: submit this single URL in Search Console and Google discovers
     every child sitemap.

     sitemap-listings.xml (every active aggregated listing, ~32k URLs) is
     deliberately NOT advertised here. Two months after submission Google had
     indexed 0 of 36,562 listing URLs while the 356 original content pages went
     unindexed too: the listing bulk is syndicated from the source portal, so it
     cannot win on its own, and it buried the pages that can under a 90:1 crawl
     surface. The file is still generated and reachable at
     /sitemap-listings.xml, and listings remain linked from every city page —
     this only stops us pushing 32k duplicate URLs at the crawler. Re-add the
     <sitemap> entry once the content pages are actually indexed. -->
