  METALLAI sitemap.

  Add each new tool page here as it ships, with its own <lastmod>. The remaining
  Tier-1 calculators are listed in docs/MARKETING_PLAN_2026-09.md §4.
  Never list a URL that does not yet return 200.

  Every page exists in English and in Turkish (under /tr/). Both entries of a
  pair carry the same three xhtml:link alternates as the pages' own hreflang
  links. The 404 page is not listed (it says noindex).
