  NumPet — world.numlm.com

  One entry on purpose. `/create`, `/world`, `/profile` and `/settings` all depend on a session
  cookie and are disallowed in robots.txt, so listing them would advertise URLs that answer with
  a redirect for every crawler that asked.

  NO hreflang alternates: the five locales (en/ko/ja/zh/es) are served from the SAME url and are
  selected by `resolveLocale()` from the `wn_lang` cookie, the geo header and Accept-Language
  (design §9.2). There is no `?lang=` parameter and no locale path segment, so every alternate
  would point at this same address — which search engines treat as an error rather than as
  five languages. If a locale ever gets its own URL, the five links belong here and in <head>.

  `lastmod` is a fixed date, not the build clock: a redeploy that changes nothing about this
  page must not tell a crawler the page changed.
