  Purotech — sitemap.

  The site is a single page. Its language variants are addressed by the ?lang=
  query parameter, which is what the <link rel="alternate" hreflang> tags in
  index.html point at, so each variant is listed here as its own <url> carrying
  the full alternate set (an hreflang cluster must be self-referential).

  English is the bare root, not "?lang=en" — the two would serve identical bytes
  and listing both hands crawlers a duplicate URL.

  CAVEAT: translation is applied client-side by assets/js/i18n.js. Crawlers that
  do not execute JavaScript will see English at every one of these URLs. If
  organic traffic in DE/FR/ES matters, these need to become server-rendered
  pages (/de/, /fr/, /es/) rather than query parameters. See README.
