<!--
  Static sitemap-index served from /public/sitemap.xml so that the
  conventional https://www.penlabpeptide.com/sitemap.xml URL — which
  many crawlers (Google, Bing, Yandex, etc.) probe by default — returns
  valid XML instead of being intercepted by the SPA catch-all and
  returning the React index.html (which crushed crawl visibility
  May 6-16 2026, the SEO regression window).

  All real sitemap content is generated dynamically by the backend under
  /api/sitemap-*.xml. This file just points crawlers at them.
