  <!-- ============================================================
       Every page below exists in English (canonical, no prefix) and
       Spanish (/es/ prefix, same physical file, served via the
       internal .htaccess rewrite to ?lang=es). Each <url> entry
       carries xhtml:link rel="alternate" hreflang annotations for
       both language versions plus x-default, mirroring the hreflang
       tags already emitted by includes/head.php on every page — this
       lets Google read the EN/ES pairing directly from the sitemap
       instead of only discovering it by crawling each page.
