  <!--
    Only the homepage, deliberately.

    /start and /contact are public routes, but the static host falls back to
    the root shell for every path, so all three URLs currently serve
    byte-identical HTML. Listing them told crawlers three distinct pages
    existed and produced duplicate-content findings against ourselves. Their
    canonical tags already point here, which is correct — they ARE serving the
    homepage. Put them back the moment they serve their own content.

    /world-open-2026 stays out separately: the event has passed. Still crawlable.

    lastmod is the last commit touching the route's source, hand-set. Generate
    this file at build time once there is more than one URL to generate.

    Nothing may sit between the XML declaration and <urlset> above. A comment
    there is legal XML and every real parser accepts it, but at least one
    crawler reported has_sitemap:false against a version that had one.
