  Skymap is a single-page web app, so the sitemap has exactly one URL.
  It exists primarily so the robots.txt `Sitemap:` directive points at
  a real file (some crawlers warn / soft-skip when it's missing) and
  so the lastmod hint nudges crawlers to re-fetch promptly after a
  significant content change.  Bump <lastmod> when the user-facing
  README / live-demo features shift; it doesn't need to track every
  push to main.
