  Written 2026-08-22. Before this file existed, /sitemap.xml returned the React
  app with HTTP 200, the same way /robots.txt did.

  /sizeup and /sizeup-de were listed here on 2026-08-22, when they stopped
  being noindex. If either ever goes back to noindex, remove it from this file
  in the same commit: a URL cannot be asked to be indexed here and told not to
  be indexed there.

  What is deliberately NOT listed:
    /imprint, /privacy    - React routes. The app has one <title> for every
                            route, so both currently serve the homepage's title
                            and description. Listing near-duplicates is a
                            quality signal against us, not for us.

  hreflang lives in two places by design: in the pages themselves and in the
  xhtml:link entries below. Google accepts either; two agreeing sources are
  what makes a bilingual pair unambiguous. Each URL must list BOTH languages,
  including itself - a set where one side omits the other is discarded whole.

  lastmod must be a real date. A file that claims today on every crawl is
  ignored as noise. Change it when the page changes, not when the sitemap does.

  <!-- The Field Notes index. A React route, so unlike the two articles below it
       ships no server-rendered text - its worth here is that it links to both
       of them from a page the nav links to, which a sitemap entry alone cannot
       do. Restored 2026-08-22 after being removed on the 21st. -->
