  2026-09-21: one entry, matching reality. This is a single-page app
  (one index.html shell, no separate content pages) behind a password
  gate. lastmod below should be bumped ONLY when the public-facing shell
  itself actually changes (index.html, its meta tags, or what an
  unauthenticated visitor sees), not automatically on every commit or
  deploy, most of which touch backend/pipeline code invisible to a
  visitor. An auto-updated "today" timestamp on every build is exactly
  the dishonest-freshness-signal pattern this entry is meant to avoid.
