    MAINTENANCE NOTES:
    - Update <lastmod> whenever you deploy changes to that page. Google uses
      this as its primary signal for re-crawl priority. Stale or fictional
      dates will cause Google to distrust and eventually ignore lastmod entirely.
    - <changefreq> and <priority> are omitted intentionally — Google, Bing,
      and Yandex all ignore them. They add bytes and create a false sense of
      control. See: https://developers.google.com/search/docs/crawling-indexing/sitemaps/build-sitemap
    - If you add pages, add them here. If you remove pages, remove them here
      AND set up a 301 redirect or return 410 Gone.
    - Submit this sitemap to Google Search Console and Bing Webmaster Tools.
    - Reference this file in robots.txt:  Sitemap: https://iriszf.com/sitemap.xml
