<!-- Canonical URLs are extensionless: /publications, not /publications.html, and
     the bare root for the home page. Three things must stay in agreement — this
     file, each page's <link rel="canonical">, and the rewrite rules in .htaccess.
     Change one without the others and search engines get a sitemap full of URLs
     that redirect, or canonical tags pointing at pages that redirect.

     <lastmod> is the date that page's content actually last changed, taken from
     git. Keep it honest: Google only trusts lastmod if it is consistently
     accurate, and a file where every date is "today" gets the signal ignored.
     Update the entry for a page when you change that page — not all of them.

     <priority> is retained for completeness but Google has ignored it, and
     <changefreq>, for years. Neither affects crawling. -->
